Just curious. I would like to have a 22mag automatic mousegun.:)

[roscoe]

TOO LOUD!

[WonderNine]

Yes, they are loud, but so are 9mm +P mouseguns like the Kahr and .357 j-framed revolvers.

Muzzle FLASH!

The unburned powder would likely cause reliability concerns as well.

You mean like this:

The only problem with 22Mag mouse guns is that the ballistics become very similar to 25ACP.

Oops, you did say autoloader :o

[Henry Bowman]

S. Raider - How does the trigger work on that thing????

BTW, I'll be in Knoxville this weekend. Hope it's sunny!

I have heard and read that the .22 WMR round is much too long and narrow to feed reliably in an autoloader. However, there are several great revolvers calibered in the .22 WMR.

[Graystar]

.22 Mags are LONG! Longer than .45 ball ammo (proportionally speaking, the case is even longer.) Considering the amount of slide length you'd need just to be able to cycle, plus the long chamber, I'd guess that the smallest design would probably be too long to qualify as a "mouse" gun.

[Old Fuff]

Two reasons ......

1. As has been pointed out, the cartridge is too long to work well in a small pistol. Full-sized automatics are another matter, although the handles tend to be large - perhaps too much so.

2. The magnum rim-fire case is made from heavier material, and as a consequence requires a stronger hammer/striker impact to reliably fire. Again not a problem in larger handguns, but much more so in small ones.

This is the reason compact .22 Magnum's tend to be revolvers or derringers.

[Walt Sherrill]

You're talking semi-auto, right?

The length of the round has more impact on overall gun design than most anything else, and if you've got a round that is as LONG as the .22 mag, it takes just a bit more effort to design a gun that will take a slightly LARGER diameter round just as well.

Then you've got much more bang for your buck.

That being the case, you might as well go .380, 9mm, .40, or .45...


Seen the new Kel-Tec .380 version of the earlier P-32? Much more potent than an .22 magnum.

It's a simple single action revolver, so there's not much to the lockwork.

Weather looks nice for this weekend, have fun!

[JERRY]

A.M.T. made one of similar design to their automag in .30cal

it was a stainless, single action with a 7or 8 shot mag and it had a 2.5 or 3" barrel, not sure, but it was as small as your typical PPKS or whatever the smallest james bond walther was.

it looked neat and would be a good little hide out gun if it was reliable, that is what the question is here anyway.

One could be made with a long thin grip in single stack. I see no reason why not.

It could be smaller than the Phoenix Arms target pistol. With the right ammo and at least a 3" inch barrel you could have decent ballistic (better than .32ACP) and better capacity than other mouseguns. They could make a 9 or 10 shot.

[Walt Sherrill]

If you're going to have a grip long enough to accept a .22 mag, why not just go ahead and make it a bigger caliber gun?

Is "THIN" your primary consideration?

I've been lead to believe that a .22 magnum from a short barrel doesn't have performance much better than a .22 LR -- that it takes a longer barrel for any benefit from the "magnum" power to be realized. Have I been lead astray on this point?

I recall an article in a police training magazine years ago about a department that issued the High Standard derringer as a off-duty/back-up gun doing a test between the 22 LR and 22 Mag versions. The ballistics were almost identical. They went with the 22 Mag version simply for the psychological effect of the increased muzzle blast. Hoped the bad guys would think it was a real gun I guess!

[scotjute]

The .22 mag round out of a pistol is about the equivalent to a .22 lr out of a rifle. So that is somewhat of a ballistic improvement that one gets from using the .22 mag round in the shorter barrelled pistolsvs just the .22lr round. When you extend the barrell to 4", the .22 mag round begins to come into its own. The NAA website has the ballistic data for this round up to 4" barrells.

[lodwick]

The two that came from Irwindale(sp?)CA work great: the one from some other factory makes a nice hammer.

As has been mentioned, the length of the round makes loading tricky.

If I had to count on its firing, I'd use the S&W .22mag wheelgun.

Have fun with it.

[DWARREN123]

I have an AMT AUTOMAG II in 22WMR, the grip is large and it is a single stack. The barrel is 6" long and there is still a lot of flash and a very loud bang when fired. So far it has been accurate and reliable and I would not wish to get shot by it.
It is something different.:neener:

[pocketgun]

I have the Automag II with the 6" barrel. When I fire it at the indoor range, other people usually stop shooting due to the tremendous "boom" and volleyball-sized cloud of fire it produces. When I finish my string, people are usually behind me watching, then asking "what the heck is that" type questions. Now imagine how much louder/brighter the short barrel model (3.5") must be. As Walt Sherrill mentioned, when you add it all up, there are just much better choices for self-defense in a pocket pistol. It makes for some fun at the range though, and the ammo is cheap enough to let people/new friends give it a try for a mag or two.

edited to add: Cross-posted with you DWARREN123...

[Plink]

Some years back Grendel made a 30 shot compact pistol in .22 mag. Apparently it was extremely unreliable. As mentioned, AMT made autoloaders for it also. I'd assume with the long thin case, that reliability is the main issue.

"Why are'nt there any 22mag auto mouseguns?"

Because mice cannot handle the recoil!






Sorry... I couldn't resist. :o

[panzermk2]

:eek: LOL :eek:

[GEM]

I fired a NAA in an outrange with partitions between the shooters. I thought I blew up. I swear the hair on my head was blown backwards and I felt blast around my glasses. It was much worse than firing a 9mm in a large pipe - which I did at an IDPA match.

I slammed my eyes shut at the fireball.

Scared the crap out of me.
