 Beretta 92 9mm conversion to .357 sig...questions

Thinking about picking up a Bar-Sto .357 Sig barrel for my 92FS. Are there any other parts I would need to change besides the barrel...I'm assuming the 92 and 96 slides are identical. I imagine the higher powered cartridge would give the slide quite a beating, would adding a Wolff extra power recoil spring help?

For $195, it seems like a no-brainer. Am I missing something

I have no clue what the answer is, but you should think about posting this question in the handgun forum here. Probably will get more replies.

A 92F/FS won't work, you'll need to start with a 96 series frame due to differences with the feed ramps. You will need a 40SW slide as well.

Basicly a 92 isn't where you want to start.

Todd Lewis Green experimented with 357Sig converted Beretta 96's quite a bit while he was Beretta's Law Enforcement Rep. They can be made to work, but IIRC the final consensus was it wasn't worth the effort.


If you want more ompf look for a 9x21, 9x23(? perhaps) or .41 Action Express barrel, all of which should fit the 92 and offer a ballistic step up.

9x21 doesn't offer any more velocity over a 9x19 and I think 9x23 is too long for the mag well. .357 is a step up over 9mm and is known to fit in the 92.

I don't see how the 92 slide could be used. The breech face for 9mm wouldn't work with the 40/357. I think you'll need a 96 slide.

Doing a little more research, here's what I need:

Complete Beretta 96 slide ($150 - $250)
Drop in .357 Sig barrel (several manufacturers, $100 - $200)
No special mags needed, 92 mags are fine

So for $250 to $450 I'll have added .40 cal and .357 Sig to 92

Sounds like an interesting piece of hardware. Let us know how it turns out. If you have good luck I may get a 96 to mess with.
I have 2 92f's and love 'em. A 357Sig 96 would be the cats meow.

Yes, you will need a 96 slide. Check out CDNN, I believe they have complete 96 upper halves. I would get the Brigadier slide for weight and durability. I would also think you would need 96 mags but maybe the 92s will work.
