Ruger-57. No Longer Just Internet Rumor

[spyderco monkey]

I've always thought that the FN57 and now the Ruger-57 would make a good handgun for military aircrew. Lightweight, high capacity, easy to shoot for non dedicated gunfighters and potentially useful against enemy personnel and for small game hunting. 40 rounds carried on body with perhaps another 50 rounds in the survival kit.

Yes it would.

Cartridge weights:
5.7x28 = 6.5g per cartridge
9x19 124gr = 12.6g per cartridge
5.56 62gr = 12g per cartridge

So for any sort of survival application on foot, one can carry ~2x the amount of 5.7 then they could 9x19 or 5.56.

50rd boxes of 5.7 are also very compact; you could easily fit 3x of them in a cargo pant/jacket pocket. 150rds is 2.15lbs, less then 2x 16oz water bottles.

This pic provides some scale. From memory, they are about ~ 1.5" tall x 3" long.



And 500rd cases come in these wonderful little 'Textbook' sized cases, which can be easily fit into a backpack.

So could one call this reloadable 22 Magnum? 221 Fireball Short? Seems like it is a better 10/22 magnum (10/57 as mentioned) round, than a pistol self defense round. I guess I look at it for squirrel and varmint hunting.

That's a big negative. My Keltec PMR 30 22 Magnum pistol gets 1200 FPS with 40 grain ammunition. The FN 5.7 pistol gets 1650-2050 FPS with 40 grain ammunition and up to 2480 FPS with 27 grain ammunition. You guys reading 22 magnum factory ammo ballistic charts to make comparisons are forgetting 22 WMR is primarily a rifle cartridge. Listed factory specs with that round are for 20+ inch barrels.

Hmmm. OK.

Target at 25 yards. Ten rounds fired off a sandbag. Fired case for size reference. Case is 1.137" more or less.

And target at 35 yards offhand. Twenty rounds. Magazine for reference is about 5" long.

Another thing to comment on. The gun is a "chassis" gun. Not as quick to pop the grip frame off as a 320 but the idea is there. Unfortunately Ruger has no current plans for grip modules.

5.7 - 4.8" FsN barrel:


.22 Magnum - 4.3" PMR 30:


When you also factor in that 5.7 uses real, Spitzer .224 rifle projectiles, vs the really stubby .22 mag projectiles, it's clear theres a marked difference between calibers.

In terms of performance for the new Speer 5.7 Gold Dot, I suspect we will see performance similar to the old 'Elite Protector III' load, which was also a flat nose JHP profile similar to the Gold Dot prototypes that have been shown.

46gr @ 1750fps / 312 ftlbs, so a bit hotter then the Speer 40gr @ 1790 / 285 ftlbs.

Not world shattering performance, but a very compelling self defense option for 'Low Recoil Shooters.'

Tim Kennedy carries a 5.7 because it’ll go through cars and fires a 40-grain rifle round at 3000 fps out of a pistol. [emoji849]
