9x18 pistol fires 380acp.?

gunneyrabbit · Post by **gunneyrabbit** » September 27th, 2007, 12:26 am

Here is a twist that I have never heard of, there is a fellow at the Auction Arms web site who states that you can fire 380acp ammo out of a 9x18 chambered handgun. I've always been under the impression that the case and slug sizes are off to much to safely fire the 380 cartridge in the 9x18 pistol? Has anyone Else out there tried it? Does it really work and is it safe? With the ridicules prices that the manufacturers charge for 380 I think it would make more sense to just to stick with the 9x18 ammo.

It isn't safe to shoot 380 in a 9 x 18
1. dia. bullet of 380 is .355 the 9 x 18 is .363.

2. length of case 380 is 17.27 mm the 9 x 18 is 18.11 mm
and auto loader's head space on the mouth of the case not on the rim

There are very few "interchangeables" out there ... most seem to be revolvers. The only ones that come to mind are the 38/357 (in a 357), the 44Special and 44Mag (in a Mag), the 22 LR/Long/short in a 22LR revover (and sometime in other actions as well, due to the headspacing on the rim in this case) and a couple of old and anemic 32cal pistol loads that I don't know off the top of my head.

First off it is totally irresponsible of that dealer to mislead and possibily endanger people by making such a claim.

Second, as saands mentioned there are so few "interchangable" rounds (rounds that can be shot in the same gun) 38/357, 44 special/44 mag, some 22s LR/L/S.

But I found reference to the interchangable revolver that I want and it actually does shoot 9x18mm OR 380 cal (I'm not sure if 380 is 9x17 or even less). It is a Russian gun made at Tula for "internal security forces" and is refered to as the R92.

Strange looking but I want one! ;D

Tula R-92

Notes: Developed specifically for use by undercover officers of the MVD (the inheritor of the KGB’s job in Russia), the R-92 is designed for concealed carry, with an almost-totally shrouded hammer (only a grooved surface protrudes slightly above the frame when the hammer is forward), smooth profile, sights consisting of a tiny bump at the front and a groove recessed into the frame at the rear, a small cylinder, and textured, wrap-around rubber grips to give the shooter a good hold on the R-92. The R-92 fires rimless 9mm Makarov rounds; normally, these are loaded using full-moon clips, but they may be loaded and fired without using the clip. If this is done, however, the spent shells must be removed individually by rotating the cylinder one shell at a time, and then using the ejection rod to eject each round. The R-92 may be fired in single-action or double action modes, though single-action fire is reputedly quite difficult due to the low profile of the hammer when it is forward.

The R-92KS is virtually identical, but is chambered for the .380 ACP round instead of 9mm Makarov. (Note: 9mm Makarov Hi-Power rounds should NEVER be fired from the R-92.)

WOW! Now I need to do my research and find the Google that told me yesterday or the day before that it could shoot either cartridge. It never stipulated that there was a separate model for 9x18 and 380. Not that it matters...I don't think there are many around or even made!

But I'd love to have one for 9x18...another Mak shooter!!

Astra 400 chambered in 9mm Largo but could also fire 9mm Steyr, 9mm Luger and 9x20mm Browning Long.

WOW a 4fer!!

And I think that Astra is even uglier than the Tula R92! ::) Maybe a 5fer?

trent · Post by **trent** » September 27th, 2007, 11:09 pm

now I definitely want one of those r-92's!

Notice the thing that the 2-fers, 3-fers and 4-fers all have in common ... the bullets are at least the same diameter ... and not just nominally the same but actually the same (or at least within one or two thousandths of an inch).

380acp shoots a .356" bullet
9x19 (9mm luger) shoots a .356" bullet
.38 Special shoots a .357" bullet
.357Mag shoots a .357" bullet

Nagant Pistol 7.62x32 .312"
32 long .312"
32 mag (not really a mag at all) .312"
32 acp .312"

The bores HAVE to be compatible at least .... the 9x18 just isn't compatible with the smaller diameter 9mm rounds so the dynamic (don't change anything) interchangeability just isn't going to be there ... that said, there are 380 barrel conversions to make your 9x18 into the wimpier 380 ... but WHY?

By the way, Ruger made (makes?) a single action revolver that shoots 357/38 and 9x19 ... I think with a cylinder swap, but I've never owned one ...

The only interchangeable that I ever had that didn't use the same diameter bullet was a Ruger Single Action 22 that came with two cylinders (for 22LR and 22Mag) ... they both shot accurately, so the forcing cone at the beginning of the barrel must have swaged the larger 22mag bullets down a couple of mils as they went by.

Yes saands that Ruger interchangable 38/357/9mm is done with a cylinder swap. I saw one at a NH dealer not long ago pretty cool...it fits my love for multiple guns shooting the same caliber.

One gun covering 3 calibers...wow...a dream come true!

There is a company called Medusa that builds a revolver they say will fire 28 different rounds in 380, 9mm, 356, 357,38sp., 9mm largo, etc., etc., etc.. Colt then fallowed suit a similar arrangement called the Surviver with the same kinds of stats as far as ammo use was concerned. Both company's claim match grade barrels which may or may not improve the accuracy of the items. Both claim it is the revolutionary ejector design that makes the revolvers work. My guess is that they will never be big sellers but will probably be hot collector's items in the near future.

Just a fallow up to my last post, at Cheaper than dirt.com, under favorite revolver; there is a write up on the Medusa Revolver that you may find quite interesting. The gentleman states that the revolver will fire 25 different calibers and since he owned it I,m sure my 28 number is errant. Any how it's a short read and I hope you find it enjoyable.
