multi caliber semi auto pistol?

[bohicaconcepts]

I know 25 years ago H&K made a 380 semi auto (aka model 4) that also had extra slides, barrels and magazines so it could shoot 32acp, 25 acp & 22LR. I also understand that many of those old H&K guns now have cracked receivers (not sure if it is the lower or upper receiver). I also know some of the old astra WWII semi autos would shoot many different type of 9mm (but were not 100% reliable or so I have been told).
Well, I am looking for a muti caliber modern semi auto pistol that can can handle as many calibers as possible. Yeah, I know a .22LR conversion kit is available for just about any semi auto but I want even more conversions. I also know that someone (but can't remember who) was converting ruger single action blackhawks and S&W large frame double action revolvers (can't remeber which model) to handle anything close to 30 caliber handgun round (357, 9mm, 9mm largo, 380, 30 carbine, etc) But the finish product was over $1000.00.
Does anyone know of any pistol I should be looking at and where to look for it?

The Desert Eagle is a true multi caliber autoloader.

Ruger makes a Blackhawk with interchangeable cylinders for .357 and 9mm, which *should* allow you to shoot .38's .357's, 9mm, .380, and I would assume pretty much any flavor of 9mm auto round. Don't take my word for it, I'm just speculating. Best to check with Ruger.

I'm also looking at getting a .357 Sig barrel for my Sig 226 in .40 cal. It uses the same slide and mags, just have to change out the barrel. I understand Barstow makes a 9mm barrel for this particular model, but I'd have to get 9mm mags. Not sure how that's gonna work.

MULTI CALIBER PISTOL

Witness from Tanfoglio via EAA.
Buy one in .45ACP full size all steel and with just a barrel convert it to:
400 cor bon or any other caliber based on the .45acp
Or buy conversion kits for the same gun in:
10MM,
40 S&W,
38 Super,
.357 Sig,
9MM

Really nice pistol, well made, nicely finished, accurate to a fault.

check out the medusa (?)

i recall this was a revolver capable of firing many different rounds in the 9mm family

good luck finding one

.357 SIG in a .40 S&W

Am I to understand that all you need to fire .357sig in a .40 is a new barrel?
Are there any outfits that will make custom .357 barrels? I.e. if I send in the .40 barrel to my Baby Eagle, will they be able to copy the outside dimensions and make a "drop-in" .357 conversion barrel?

I believe all you need for a .357Sig is to run a chamber reamer through a 9mm barrel. And a different extractor?

I could be wrong.

That probably wouldn't work for .380 and 9 mm Makarov. The 9x19 cylinder most likely headspaces on the mouth of the case, so the shorter cases would just disappear inside the cylinder. You could shoot .38 Special in the .357 cylinder, but only 9x19 in the 9 mm cylinder, I would guess.

 

[MrTuffPaws]

If the barrel is native 9mm, can it shoot 380? The 9mm cartrage is slightly tappered, but I don't remember if the 380 is.

Have you looked at the Springfield XD?

If you have a Springfield XD40, you can buy conversion barrels from EFK in 9mm parabellum or .357 SIG. I have the 9mm barrel in my XD40 Tactical, and it works quite reliably with the standard XD40 springs.

Be aware that the conversion works from larger caliber to smaller only (i.e., no .40S&W barrels for a 9mm XD).

IMI Jericho 941. Came with seperate barrels for 9x19 and .41 Action Express.

Try Peter Stahls multicaliber 1911's, don't know of any importers bringing these into the U.S. market. At one time they were available through Springfield Armory.



Here's a Browning High Power that's available in 9mm, 40S&W, Stahls .22, Ciener .22 conversion. 357 Sig barrels can also be had.

 

[JohnKSa]

Most 10mm pistols will also shoot .40S&W and .357SIG with a barrel and possibly a recoil spring swap.

If the barrel is native 9mm, can it shoot 380? The 9mm cartrage is slightly tappered, but I don't remember if the 380 is.

It CAN, but it's not a good practice and puts unusual stress on the extractor. It can also lead to an unsafe condition in the worst case. I'd do it in an emergency if that were all I had but since .380 costs more than 9mm, I don't see the point otherwise.

I've actually been toying with the idea of trying to build a traditional Browning (not Peters-Stahl modified version) 1911 for multiple calibers, but it'd probably "bottom out" at .38Super and require a different slide for each dimension of overall cartridge (thinking 9mm/.38Super/.40S&W might work on the same slide, then .45ACP/Super and 10mm sharing another.

Ideas, anyone? Thoughts? Anything?

I have an HK4 w/ the barrels & mags. I stopped shooting the 380 after I heard about the cracking issues. But it is ALOT of fun.
Out of current day multi caliber pistols, the only one I know of is the SIG 229 in 40/357 sig.

 

[mp510]

It is also possible to convert a Makarov from 9x18mm to .380 or .22 LR.

 

[Glock_10mm]

The glocks have alot of options when it comes to barrel conversion.

Glock G20/G29 10mm - .357sig, .40s&w, 9x25 Dillon, 22lr (with conversion kit)

Glock G21/G30 45acp - .40 super, .400 corbon, 10mm, 22lr (with conversion kit)

Glock G22/G23 40s&w - 9mm, .357sig, 22lr (with conversion kit)


The top two take 4 calibers via barrel only + 22lr with a conversion kit.
The bottom takes 3 calibers via barrel only + 22lr with conversion kit.

There are lots of other glocks with conversions as well, but these offer some of the most choices.

I know you want an autoloader, but if you can find a Phillips & Rodgers Medusa 47 revolver, it handles all things in the .38/.357/9mm range. (well almost - have to be nominal .38 +/-.02 for the shell too so no .357sig or 9x25 dillon, etc). They turn up now and then and run between $800-1200. They officially handle 20 calibers, but can really shoot more like 40 different calibers (some just at a loss of accuracy). I've heard the .32acp even will fire from one, but not well. again it is a revolver though, and they turn up on gunbroker once every 3-4 months or so, so their not all too common. I hesitated and didnt buy the last one, but will buy the next one I find!

 

[Davo]

Is there a 1911 in .45 that can be quickly converted to 9mm?
