    I recently picked up a storm Lake 357 sig conversion barrel for my Glock 22. I absolutely love it. There’s actually less felt recoil and torque then with 40 Smith & Wesson. Not to mention it’s a hot/powerful little round. My only concern is increased wear as compared to 40 Smith & Wesson. I plan on running 357 sig. with its own recoil spring. I also plan on changing it every 2000 rounds. Is there anything else I need to be concerned about? I just don’t want the pistol to prematurely wear out. It’s a generation three RTF2

    Don't be concerned with "wear". I have a Lone Wolf barrel for my G22 & G35. All I swap is the barrel, to fire .357.

    Your Glock will outlast you, no matter which caliber you fire.

    :cool:

    With the scarcity and price of ammo now both you and your wallet will wear out before you wear out a Glock shooting 357 Sig ammo. For example at .50 per round it would cost $10,000.00 to shoot 20,000 rounds of 357 Sig. That is enough money to buy at least 15 new G22s and your gun wouldn't be half way worn out.


    You might want to consider picking up some of this fine 357 Sig SD ammo while you still can, it's starting to get hard to find on line.

    When I installed a Wolff stainless steel guide rod and Wolff 20# recoil spring in my .357sig it made a great pistol an awesome one. It is nearly the equivalent of 9mm +P+ in felt recoil, but with a clear gain of power.

    In my Sig P229, I really like 357 Sig. Underwood has ammo in stock for it too. The 357 Sig will reach its full potential. And it is still nice to shoot.

    Yeah, I think it will be perfect for winter carry. I’m going to pick up some 125 grain gold dots. I already have a box to get me started. I also ran a box through the gun to make sure they would function. I also picked up some speer lawman 125s.

    There is really no addl wear. Slide soeed is close on both calibers. Recoil impulse is a bit diff, I find it easier to shoot than 40 in identical platforms. A conv bbl is how I was introduced to the 357sig. Then I bought a p239 & then a g32. I think my p239 is my fav, but a conv bbl in my Delta is about as good as 357sig gets.

    Underwood also offers a larger variety of 357 Sig rounds than anyone else. My personal Underwood SD rounds are the 125gr Gold Dot and the 65gr Xtreme Defender with it's 2100 FPS velocity.

    What's funny is that now .357 sig seems to have dried up. 40 S&W seems to be available still. At least online.

    i successfully ordered from Underwood about three weeks ago. Last time I checked .357 Sig was still available in the 125gr Speer bonded. that’s about all they had in stock though.
    I just checked and it’s still available.
    Just an FYI, though I’d like to get another hundred rounds or so.

    Just stopped by a local gun shop:
    Blazer Brass 9mm fmj: $25/50. Had a pallet of it.
    Federal AE .357 Sig fmg: $24.95/50.
    Ha.

    Oh, xm193 was $600/1000. Had a bout a dozen cases. Also a pallet of
    Hornady Frontier 68 gr fmj. Yes, 68 gr.

    I am thinking of getting a storm lake 357 sig barrel for my 23, so is the 23 mag and extractor good for the 357 sig round?

    All you need to do is swap barrels. The .40 357 Sig caliber swaps are the only ones officially approved of by Glock.

    I have a good stock of 357 Sig ammo including some of these fine Underwood rounds as well as some of their other products but seeing these hanging around is tempting!

    It will work. Just make sure to fire a few hundred rounds through the set up before trusting it. I’ve had good luck with my storm Lake barrel

    I also had a Sig 229 and 239 in 40cal and bought a 357sig factory barrel for. I loved it. I sold both of the guns. Now I have a Glock23.3 that I bought a 357sig barrel for, it is an azz rippin round. I also just got a 9mm conversion barrel for my G23,i haven't shot it tho. Anyone that hasn't shot a 357sig round neeeeeeds to.

    I forgot to answer your question. The 40cal mag works flawlessly with a 357sig round. I just couldn't stand it and had to buy 357sig mags, it just keeps everything straight in my little brain.
