Absolute smallest centerfire ...

[Swing]

Hey pals. Out of curiosity what pistol is the ...

• Absolutely smallest, dimensionally: width, depth, height. And:
• Automatic. No wheelguns, manually operated repeaters, single-shots, or derringers.
• Centerfire. No rimfires of any kind. So, we're looking at .25 ACP, .32 ACP, et al.
• Currently available in the United States. Currently available would include current production, recently produced but discontinued, and/or readily available on the used market. "Readily available" would preclude custom pieces, ancient models, pistols produced in very small numbers, etc.
• Weight, for this discussion, is immaterial, though odds are it will be light considering the size.
• Materials, for this discussion, is immaterial. So steel, polymer, alloys, etc. are options.

Thanks!

EDIT: Whoops. I thought you were asking what caliber was the smallest. My bad! Although, personally, I think that is the more interesting question.

I'll leave my original response below for the sake of posterity.

.22 TCM?

https://en.wikipedia.org/wiki/.22_TCM

Also, .22 Hornet, though the TCM is shorter...

Oh, this one is neat, although it doesn't qualify due to not being commercially available (discontinued in 1938): https://en.wikipedia.org/wiki/2mm_Kolibri

Interesting. Though I am looking for pistol not cartridge.

Search 2mm Kolibri on YouTube. I'm pretty sure it's a center fire, but memory fails me more than I'd like to admit.

How about we start with the FN Baby Browning and go from there?

https://en.wikipedia.org/wiki/FN_Baby_Browning

Length: 4.1"
Height: 2.8"
Weight: 9.7oz

That is my hunch too. That and the many clones/derivatives (e.g., Bauer) out there. But, maybe, or not, there is something smaller.

Neat, but not produced since before WWII. For viewing enjoyment, though:

Walther Model 9 - 25 ACP

Baby Browning is on the left and Walther Model 9 on the right in both photos

Neat-O. I, ever so vaguely, recall ultra small Bernardelli autos in that form factor.

 

[AlfonsDeWolf]

You mean one that actually works and is reliable?

OoPs, I missed the "currently available" part I guess.

The Baby Browning and/or copies is likely going to win the day, it'd certainly be the smallest I can think of that would be readily available.


EDIT:
Thanks for finding the video, I was on my phone last night as well as feeling lazy. I haven't seen it a while.

 

[bannockburn]

I would think the PSA-25 would be the smallest centerfire semi-auto currently available.

 

[MedWheeler]

I agree about the Baby Browning and clones, including the currently-produced PSA. The Bauer version, though discontinued in 1984 (and it's Fraser namesake in 1986) is still readily-available on the used market.

I don't know how "readily-available" the Walther 9 mentioned in post 8 is.

 

[stchman]

The Kel-Tec P32 is:

5.1" long
3.5" tall
0.75" wide

It weighs in at a hefty 6.6oz, that's pretty small and light.

 

[hdwhit]

RG-25, .25 ACP No longer made, but still available.

4.5" long
3.5" high
0.8" wide

At 11.15 ounces, it is pretty heavy.

 

[AlfonsDeWolf]

The keltec .32acp would get my vote, either that or shrink my hands, but I'm not sure that's following the O.P's line of ?ing

 

[lincen]

Bernardelli VP or Vest Pocket 25 acp.

Length 106mm = 4.173"

Width 15.5mm = .610"

Height 68.5mm = 2.697"

Grips 20mm = .787"

Weight 261g = 9.207ozs.

They have not been imported since the 68GCA but are frequently listed for sale online. I have bought two this year, very reliable little pistols.

That is a good graphic aarondhgraham, thanks for the link.

I believe your answer will depend on who currently produces a .25 ACP pistol. Not many do today as it (and .32 ACP) have been beaten in popularity with the .380's out now. My guess is going to be the Baby Browning, most other .25 auto's are just clones of it or are made of pot metal and bigger in size.

My other comment is with how small the gun is, you wont be reloading it quickly, so it's kind of pointless to leave out the little NAA revolvers for consideration in carrying.

I think this is the latest version of the pocket auto comparison.

Dunno if this has been mentioned. Late 2016 arrival so not "currently available" but still.

From the OP:

Absolutely smallest, dimensionally: width, depth, height.

Anything bigger than the PSA .25 (Boberg, Kel-Tec P32, etc.) is out. Too many are answering as if he's looking for a concealed-carry weapon, and are factoring caliber as well. He's not.

The OP said this was "out of curiousity", not that this is being considered for carry. That being said, I still believe that, using a second magazine, I can certainly reload my Bauer 25 faster (and with one more round) than I can unload and reload my NAA mini-.22 revolver. In fact, I bet I could do it from the same magazine. Now, if my NAA was a "Sidewinder" model, or a break-top, that would certainly improve its time, but I doubt it would still get near Bauer-time if the Bauer had a spare magazine (and the revolver would be bigger.)

I have the berrata and colt on " 00 " frame - both are 22 lr thou . Next smallest is my
25 ACP - it is heaviest so my wife only carries in cold weather . If is is hot - one of the 22's w / snake rounds in yard .
