Also, other projects (without images)
U-2 rifle - one of special sniper rifles, works in pre-WW2 period. Cartridge - 7.62x80, base diameter ~14.5 mm. Idea - very long range, accuracy, and, lighter than weapons in 12.7x108 (information of Russian historicist Ruslan Chumak). 10-round magazine. Also, worked at new ~10 mm special cartridge.
Full-auto grenade launchers, 45, 65 and 76.2 mm.

Markevich shotgun (~30th) - 5-round revolver, gas-operated, 24, 20 and 16 gauges, 70 mm case, choke - muzzle break compensator, weight in 20 gauge - 2.8-3 kg. Not realised.
GARS - Gurevicha Aktivno-Reactivniy Snaryad (Active-Reactive Shell) - rocket for shotguns, for shoot of light-armoured and light vehicles, infantry groups, etc. Worked at WW2 by Evgeniy Samoylovich Gurevich, for partisans.
Baranov "pocket mortar" - based on OSP-30 signal pistol, use special mortar shell in 4 gauge case, 3 inch lenght. Also, used a special aim. Projected in 1943, Soviet Kampfpistole, not produced. But, in WW2 produced light incendiary rocket for signal pistols.

"
The Lower picture is one of a number relating to German projects to develop small arms capable of firing around corners. This worked somewhat better -- if I remember corectly the attachment was called a Krumlauf -- and they were actually issued to field units in the last months of the war.

To tell the truth, I'd love to see an additional region on the site covering small arms, artillery, and similar systems!

Regards, Abraham
"

Those "corner guns" were primarily issued to self-propelled guns like Panzer Jager to get rid of pesky Russian infantry climbing on top, trying to pry open hatches, etc

Vladimir Karlovich From, LMG (1917) - Villar-Perosa + Gast + Gebauer. Or, maybe, grandfather of TKB-059/Pribor-3B :)
8.4 kg, triple-barrel, crankshaft, rate of fire - regulable, to 900 rpm, 7.62x38R Nagant "upgrade", with "full power" - 18-inch barrels. Magazines - 50-round, fast-loading. Projected for infantry, scouts, cavalry, motocyclists ("can montage on rudder") and air forces, idea - lighter than Maxim M1910, and, lighter cartridges, but, large distance. I haven't data about muzzle velocity, in my calculations, with standart 7-7.5 g bullet and standart load, it's a 430-460 mps, but, range - to 1200 shag (854 m) - very big for standart cartridges. I don't know, what is a "upgrade". Maybe, it was a "long" Nagant*:
25672053_24058.png
25672123_25014.png
*Soviet 7.62x38R cartridges - 5.5 g bullets, 410-415 mps standart and 550 mps long. Also, in early 30th created "magnum" 7.62x38R with powerful load in standart size, 7.5 g, 320-370 mps, and, I haven't data about analogical cartridges in WW1. By my calculations, Soviet "magnum" in 18-inch barrel - it's 500-562 mps, "long" cartridge - 858 mps. (.327 federal magnum - cartridge in 7.62x38R size - with 100 gr / 6.48 g bullet in 4 inch barrel - 1604 fps / 489 mps, in 18 inch barrel - 2186 fps / 666 mps; or, with 115 gr / 7.45 g bullet in 4 inch barrel - 1451 fps / 442 mps, in 18 inch barrel - 1880 fps / 573 mps)

Up untill now we've seen a lot of the bigger hardware in this section, but I was wondering if anybody had informations on secret projects regarding small arms and machineguns?
The only thread of interrest I managed to find regarded the Girojet project.
So if any of you guys have such info, feel free to post it here.

Thnx
Wouter
www.forgottenweapons.com covered the Gyrojet carbine on August 27, 2015 and the Gyrojet pistol on September 8, 20114. They proved wildly inaccurate and only a few of these futuristic firearms sold to civilians. These days Gyrojet ammunition is rare and ridiculously expensive.

The only significant production run was A/P25S-5A Gyrojet flare guns that were issued to USAF air crew for many years. White, green, blue and red flares rose to an effective altitude of 1,500 feet.

That Steyr IWS 2000 hardly counts as a “small arm.”
The usual dividing line is at weapons that can be carried by one man and fired from the shoulder. At 18 kg (39.7 pounds) that Steyr is too heavy to be fired from the shoulder.
The other dividing line is around .50 (12.5 mm) because a lot of black powder rifles were around .50 cal.

Canadian gun laws severely restrict civilians from owning (smokeless powder) modern rifles more than .50 calibre. The RCMP banned Barret .50 cal. rifles for civilians, but another dozen manufacturers introduced large rifles - firing Browning .50 cal. heavy machine gun ammo - that circumvent that law.

Shotguns are under a separate category under Canadian gun laws, because they are loaded much lighter than rifles and have much slower muzzle velocities. CGL don't limit shotgun magazine capacity because only tube magazines were available when the law was written. Then some dastardly American invented a shotgun with a box magazine!

Shotguns are generally considered small arms:
10 Ga = 19.69mm
12 Ga = 18.53mm
16 Ga = 16.83mm
20 Ga = 15.63mm

And a lot of black power rifles were considerably over .50 cal:
Brown Bess (4.3m built) was .75 cal
Springfield Pattern 1795 (150k built) was .69 cal
Dreyse Needle Gun (1.15m built) was .61 cal
Pattern 1851 Minié was .70 cal
Only around the ACW do you start to get calibre dropping below .60, and initially not by much.

Shotguns go up to 40mm, if you count a sawn-off M79 with flechette rounds as a shotgun.

I believe there is a .950 JDJ hunting rifle too. :D

Dear DWG,
You do have a point about large calibre, black powder rifles, but the only significant batch of black-powder rifles bought by the Canadian Army and Northwest Mounted Police were breech-loading .577 Snider Enfields bought in 1873.
By the turn of the century, they were replaced by a series of .303 calibre Lee-Enfield, bolt-action rifles with box magazines.

Isn't the larger 23mm a 23x152mm?

I have information about work at 23 mm sniper rifle with 30x165 mm case, with new long "bullet", but, I haven't information about work at 23x152 or other old cartridges. 23x152 - between 23x115 and 30x165 cartridges by power, and, military consired this cartridge unnecessary.

As Canada only came into existence with Confederation in the 1860s, the Army missed the time slot for larger calibre Black powder weapons. However the pre-Confederation Militia and Fencibles will have used whatever the British Army handed over, or privately bought weapons (whether individually or by wealthy commanders or benefactors), which undoubtedly would have been larger calibre. The Brown Bess carbine was developed for operations in Canada and definitely equipped Canadian Militia during the War of 1812.

Looks like you're meant to hold it with the butt and use the opposite hand to manipulate the trigger when it is fastened to it's support "board" (or more likely ship's rail).

About early Russian semi-auto pistols and submachine guns
In 1908 in Russia builted experimental full-auto pistol, based on Borchardt-Luger model 1904 and Mauser model 1906. On tests it was a very bad weapons, with very fast rate of fire, very small magazine and very unrealible. And, started work at special system. Engineer Frolov at 1912 constructed full-auto pistol-carbine in 7.62x38R Nagant, fith 20-round magazine. It was a delayed-blowback, rotating-closed system, maybe, earliest Russian SMG, or, grandpa of Stechkin APS :)
In Izhevsk at 1911, based on details of Browning M1906 pocket pistol, created semi-automatic pistol in 7.62x38R.
But, works at small arms in 7.62x38R Nagant was a closed. Russian army going to new weapon system, with two calibers - 6.5 mm for rifles and 9 mm for pistols. Works at new calibers was a braked by WW1, and not ended.
In 1915 workman of Kuban cossack host Molokov suggested a "light machine gun", named a "Kubanets" - like a Mauser C96, full-auto heavy pistol, in 7.62x38R Nagant, with 33-round magazine. Reaction on this weapon - "Very interesting, but, We can't working on this gun today" - it was a, maybe, hardest period for Russian industry in WW1, and "Kubanetz" was left for later.
Also, in 1915, general N. I. Yurlov proposed weird "small machine gun "Jakob"" - based on Nagant M1895 revolver, belt-fed.
Also, inventor Domanevskiy proposed a "double Nagant" with second barrel, second cilinder, with full load - 14 cartridges. Other Domanevskiy's weird gun - "electrical revolver" - it's a Nagant in 7.62x38R with 7-round cilinder, or in .22 Velodog with 15-round cilinder, in special trunk with lamp.
"Pistole-shahka" - suggested by D. I. Nakvasin, shashka + 7.65 mm Browning pistol with 12-round magazine in handle
"Shashka-machine gun" - suggested by V. I. Lisenko, shashka + 9 mm Browning pistol with 12-14-round magazine
Also, engineer Korovin in 1912 patented a self-loading pistol.
I thread about "Mauser C96 in 7.62x54R". Yes, it's a semi-mithycal gun, "Tsarist's Desert Eagle". I don't know about system, but, I think, it was a sawn-off rifle - maybe, semi-automatic. In France created two "SMG", sawn-off RCS M1917 rifle and Chauchat M1915, with 8-round clip and 20-round mahazine, in 8x50R Lebel, in German created C96 in special 7.63 mm cartridge with case between 40 and 44 mm, with 1.5 g (23 gr) load - and, maybe, analogical weapon constructed in Russia.
And, other semi-mithycal gun... Automatic pistol from early XVIII century. Yes, I know, it's a very weird, but, 1) in Russia in XVII maked a revolver and magazine pistols and muskets, 2) in England in 1664 created automatic gas-operated revolver. Peter I traveled to England and communicated with British sciencists and engineers, and, maybe, he wanted something like a this gas-operated revolver.

33 rounds of a rimmed cartridge is gonna require one hell of a magazine for a pistol, though Tokarev did fit 21 in a reasonable-looking mag for the M1927.

Wrong era for the Tsarist nickname, but possibly this thing? An SVT-40 hacked down into pistol form, with a PPSh barrel shroud welded on. No idea where it came from or who made it, but I'd imagine firing it would be an "interesting" experience. Looks like it'd be effectively a bolt-action though, don't see any sign of a gas system under that shroud.

Also, about pistols and revolvers:
Korovin double-action semi-auto pistol, 1912, British patent:
984058.jpg
Horman (gunmaker in Tula) 1864 experimental revolver, with paper cartridges:
18216173.jpg
Other revolver of Norman, rifle and shotgun with removable barrels and reusable cartridges (load of cartridge front):
IMG_20191128_094530.jpg
Lenght of smooth-bore 16 mm barrel - 900 mm, lenght of rifle 17 mm barrel - 692 mm, weight with smooth-bore barrel - 3.07 kg. In Tula in 1860th constructed analogical handgun.
N. I. Goltyakov revolver, 1864, project:
69.jpg
Other Nikolay Goltyakov revolver, 1875:
DSC00754.jpg
Other revolvers from 1860th:
Selivanov, Bezborodov pin revolvers - variants of Lefacheux revolvers
Wishnevskiy - variant of Lefocheaux revolver, but, with central pin. Small serial produce. Photos of this revolver:
Chagin 1866 pin revolver - light-weight (1.04 kg) six-shot revolver, with hand-operate rotate of cilinder. Cartridge - analog of Wishnevskiy cartridge, caliber - .43, but, I think, it's in Russian system of calculation - .44 S&W revolvers in Russia named a 4.2-line, or .42 caliber, and, I think, Chagin revolver was a .45 caliber, in American system.
Gorynov 1861 percussion revolver - double-action .35 (maybe, .37) caliber revolver, light-weight (1.2 kg), of 19 parts. Six-shot, paper cartridges, cilinder-conical bullets. Gorynov shoot 180 rounds from this revolver, without damage.
Goltyakov (I don't know, who is this Goltyakov - was a many gunmakers with this surname) 1890 revolving rifle - top-break (based on ideas of Russian S&W revolver), .42 Berdan, six-shot.
Kun and Zalybovskiy 1890-1895 revolver - top-break, .44 Russian with smokeless load, lighter than S&W №3.
Rachkov revolver - 1890th, S&W №3 in 7.62x38R Nagant cartridge.
Between 1900-1914 worked at uprades for Nagant M1895. Engineer Zibin (Rus. Зыбин) in 1910 built swing-out revolver with fast extraction of cases.
...
Also, pistols:
Medvedev 1837 - multi-barrel pistol, "load at once on 50 shots"
Yasherov 1848 - pistol "with ingition tube on 12 shots" - I think, "duck paw" pistol (in Russia named a "death hand", "рука смерти")
Grebenskiy 1880 - weird gun, lever-action, with tube magazine, hinged down barrel.
Mosin 1891 - six-barrel .30 cal peperbox.
In 1860-1870th worked at single-shot .60 caliber pistol with CF cartridge, I haven't data about construction and ballistics. Also, tested American Berdan .42 single-shot pistols.

33 rounds of a rimmed cartridge is gonna require one hell of a magazine for a pistol, though Tokarev did fit 21 in a reasonable-looking mag for the M1927.
Maybe, it was a pan magazine.
Later, gunmaker Nikolayev created SGM in 22LR with 50-round mag:
21489560_15279.jpg
21489560_15292.jpg
21489560_15304.jpg
21489604_15387.jpg
21489604_15393.jpg
Also, springless magazine for unknown LMG, 7.62x54R, Kazarin patent, 1933/1967:
IMG_20191130_190439.png
Maybe, in "Kubanets" used analogical magazine.
...
Experimental variant of PPSh - pistol handle and experimental magazine:
news-698_1.jpg
Also, in 1942/43 created belt-fed PPSh variant with MG34/42 details.
Also, one inventor suggest huge helical magazine for PPSh.
...
Benardos bullets for M1891 rifle, flechettes and tube bullet (right), 1890th:

Suggest of Iskirskiy, 1915 - light-weight LMG with combine feed - clips of M1891 rifle and belt of M1910 Maxim gun - Russian WW1 minimi in 7.62x54R. Belt-fed system - rotating, closing - double, construction without screws, easy to service.
00000301.jpg00000302.jpg00000303.jpg
Rifle/LMG (with full-auto firing), constructed by architech M. G. Kalashnikov, 1916:
Kalashnikov 1916 rifle.jpeg
You can see - based on M1891 rifle, delayed-blowback, with 14-round magazine, based on ideas of Chauchat M1915 LMG. This rifle was ordered to experimental produce to the Sestroretsk plant in late 1916. Very interesting system for replacement of massive Fedorov system.
...
Other ideas and projects:
- Create 100-round pan magazine for Lewis LMG for aircrafts
- Rebuilding of Lewis LMG and 50-round magazine to 7.62x54R
- Building of shortened 7.62x54R with immersed bullet, for use in Lewis (overall lenght ~69-70 mm)
- Create of LMG based on Maxim M1910 - project of Kabakov, 1913, with deleted water cooling, butt, pistol handle with trigger, box mount, with 200-round belt.
- Create of LMG based on Colt-Browning M1895 - experimental, 1916, butt and drum magazine, with two 100-round belts. Magazine for this LMG:

9x30 "Grom" ("Thunder")
Cartridge for A. Shevchenko weapons - project of pistol, and "Gepard" SMG. Based on 9x19 and Russian 9x21 cartridges, use bullet from 9x21.
Data of 9x30 in "Gepard" SMG (pistol)
Weight of bullet - 6.5 g
Muzzle velocity - 600-610 mps (500 mps)
Muzzle energy - 1170-1209 Joules (813 Joules)
Overall lenght - ~41 mm
...
6.5x30
Parent case - 9x30 "Grom". Other cartridge, also used in Shevchenko pistol and "Gepard" SMG.
Weight of bullet - to 5 g - maybe, lighter.
Muzzle velocity in pistol - 780 mps, in "Gepard" (based on proportions of 9x30) - 936-952 mps.
Ruslan Chumak told about works of assault rifle with "recoil shifted pulse" in 6.5x30. I haven't data, what is this a system, but, I think, it's not based on Nikonov AN-94 assault rifle.

...
4.6x30
Small-known project, I don't know, it's a based on 9x30 case, or based on German 4.6x30 H&K cartridge. Double-environment cartridge for pistol for special forces.
...
Unknown ultravelocity cartridge for "Gepard" SMG - 1500 mps (!), maybe, smooth-bore. Maybe, it's a 4.6x30 cartridge with light (1-1.5 g) bullet.
...
5.45x30
Cartridge, or, maybe, two cartridges, one based on 5.45x39 case, shortened to 30 mm, with standart 3.4 g bullet, muzzle velocity 670 mps (415 mm barrel). This - or, other 5.45x30 - used in project of Alexander Shevchenko heavy pistol, gas-operated, hard-closed, early 1990th.
...
9x19 7N31 cartridge
Maybe, most famous Russian PDW cartridge, based on 9x19 Parabellum case, 4.1 g bullet, 600 mps, 738 Joules. Also, based on this cartridge created underwater 4.5/4.6 mm cartridge for GSh-18.
...
.45 ACP Russian
For OTs-69 LMG (and, maybe, for OTs-122 pistol) created .45 ACP overpressure version with supersonic bullet - maybe, Russian analog of .45 Super or .460 Rowland. By my calculations, it's, maybe, 8 g bullet with 600 mps and 1440 Joules.
Photos of OTs-122 pistol - you can see two .45 barrels. Maybe, one - for powerful cartridge, other - for standart.

...
15-15.5 mm Kochkin cartridge
Project of superpowerful cartridge with AP bullet, weighted to 35 g. I haven't data about parent case, ballistics, but, I think, it's more 3 kiloJoules energy - most powerful .50 AE loads is 2.9-3 kiloJoules.
