    I really like my G31. While it's not yet at true .357 mag numbers. it's clawing on the heals of the 60 Pro and has the 686P in it's sights.

    I have been nothing but impressed with the G31. I'm now reloading for it. And there is so much head room to play with it should be producing true 125gn ,357mag numbers and still retain combat accuracy. The pistol and it's round have been a joy to work with.

    The round seems to be inherently accurate. And the Glock OEM chamber seems to support the round very well and be easy on the brass. And it seems the barrel it's self is very fast! I slugged it out last night. It seems very true and measured out perfect! I did a chamber poor and it to was perfect. Looks like Glock put a match grade barrel in my old 3rd Gen 31. :)

    While many bag on the new Smiths. I have owned older Smith's, Colt's and DW's as a younger man. And I can't find fault with the newer Smiths. My 686P as seen 99% full house H110's and those pesky soft and slow 2400 loads. :) The wife's 60 Pro has had about 70% of it's range time on real .357's also. She shot the G31 today with loads hotter than anything you can get retail except for Underwood. And she now wants a smaller version and told me I could have her 60 Pro as soon as I got her a Glock .357 Sig.

    I don't have epiphany moments very often. But when I do. It's like a baseball bat to the back of the head. Glock and there support of fad chamberings has woke me up. There is no reason for me to ever buy a 9mm or 45acp. And I was never a fan of the .40 short & weak.

    Before me is .357 Sig and 10mm. My life has got much simpler. :)

    luckily underwood helps me with my .40 cal issues. their +p .40 rounds pack quite the punch themselves.

    Curious as to what powder you're using?

    I'm a big fan of power pistol for the 357 sig. AA#9 works really well too, but you can't quite fit enough of it in the case to get loads REALLY smoken like you can with power pistol.

    I've got my sights set on a G35 and a 357 sig barrel next. :D

    I have had good luck reloading for the 357 sig using bulk 9mm 124 gr bullets, and it makes it almost as cost effective and shooting 9mm anyway. I recommend checking out reiners 124gr fp for a cheap practice round. I usually push mine with #7

    Good stuff, blastfact. I like the following for .357SIG:

    Blue Dot
    AA #7
    Power Pistol

    I don't like to load nuclear loads, and am pretty happ with e 125 gr. round jetting along between 1300-1400 fps.

    Whenever I am loading this, it's usually in conjunction with 10mm and .45ACP, since the press setups are fairly similar, along with the components I am using.

    357Sig is a great round for sure.

    Right now I'm working with Longshot. All my research indicated Longshot was a near perfect powder for the Sig round. And so far thats the song thats been playing.

    I have Blue Dot, Power Pistol, Unique and others to work with down the road.

    Welcome to the really dark side!

    I took a coyote and a wild boar with 357Sig Golddots. Impressive!

    Using the skull of a moose (archery kill) I shot 357Sig Gold Dots into the brain cavity from the front and side.

    Over the years I have heard many stories of moose shot in the head with everything from 44 mag to 7mm mag and they walk way after the bullet bounces off.

    Granted, I placed my shots carefully, but the crux of the issue is, the 357Sig Gold Dot has the power and moxie to get to the moose's brain matter.

    The FBI tests show this cartridge does a great job through heavy clothing and car glass.

    A super benefit is the pyramid shape of the 357 SIG enhances feed reliability.

    I've got two S&W 357 Magnums (65-3 3", 640-1).
    Glock G27 with two 357 barrels.
    Sig P239 357,
    Twin HK P2000 357s,
    and a HK P2000SK 357.

    It's an easy caliber to love.

    I just picked up my first 357 in a G33 last weekend. I'm very impressed with the 357 Sig round and I generally only shoot 45's. My new 30S and other 45's have been in the safe since I picked up the G33, as I wear it everyday!

    I was hesitant about the .357 SIG when I was buying a new Glock in early 2012...I actually was leaning toward another Glock in .40 SW. I too can state after a year and a half that I have nothing but good to say about my G31 Gen 4 and the .357 SIG round.

    Here's my G31 Gen 4 with Streamlight TLR-4 tactical light/laser.


    I added 6.9mm Glock OEM night sights and the TLR-4, with which I also am extremely happy. The TLR-4 is a perfect fit and doesn't budge even when firing the hottest loads. I later added the Glock "+" magazine extension to several 15-round magazines for 17-round capacity. I did that not because I expect to need it, but because it seems to cause anti-Second Amendment nit-wits to get their panties all in a wad. :cool:

    With respect to commercial ammo, for personal defense I am wholly satisfied with Underwood's .357 SIG JHP. Though it's rated in Underwood's catalog at 1475 fps, I get 1565 fps / 680 ft-lbf from my G31, chronographed ten feet in front of the weapon. I have to use a GP100 with six-inch barrel with Federal 125 gr. JHP .357 Magnum ammo to get better from a revolver. My SP101 with 3-inch barrel firing the Federal round does not match the G31 with Underwood ammo. Unfortunately, Underwood for the past 11 months has mostly stayed out of stock.

    Of'll want to get a G22 barrel as the only part you'll need to add .40 SW capability.

    I tend to stick to the old standards; 9 mm, .40, .45 ACP, etc. Two calibers that have my attention lately though are .357 Sig and 9X25 Dillon.

    OP, what is the prefix on your serial number?

    My 3rd Gen G-32 OD is the one handgun I'll never part with. The .357sig round and G-32 credibly cover a whole lot of possible scenarios.

    I'd love to see one of new upcoming Glocks be a G35-type in .357 SIG. It wouldn't take too much effort by Glock to make that happen.

    Are any of you using a conversion barrel to shoot 9mm for practice out of your .357's? I don't have a subcompact as yet and have been considering a 26. The .357 has got me interested though and the 33 is a possibility.

    A number of you are obviously handloaders so the cost difference may be minimal, but for the rest of us it would be nice to run 9mm through at the range. I know people who are doing that with .40's so I figured it you work the same. Just looking for some comments from people who are doing it with the sig.
  19. Slalom.45... I have a G23 in .40 S&W...never use it that way...I bought a Storm Lake conversion barrel to shoot 9mm and some G19 (and I have G17 magazines)...mine works 100% with Speer Gold Dot and Speer Lawman 124GR 9mm...

    I then purchased a GLOCK 32 barrel to shoot 357 SIG through my G23 (wannabe G32 :D) and this is the configuration I carry mine in...

    I will add that my G23 when set up for 357 SIG needs either G32 (or in my case G31 magazines that I carry to reload) as the two LE/Gov't marked magazines made for my G23 were not 100% with Speer Gold Dot and Speer Lawman 125GR 357 SIG cartridges...

    When I use the proper follower'd GLOCK 357 SIG magazines, my wannabe G32 works perfect...

    Hope this helps your decision...

    I like how easy it is to switch between .357Sig and .40 with different barrels.
