    Hey gents recently the Glock 32 has caught my eye. Now I have been a fan of the 357 mag ever since I was a young kid learning how to shoot with my grandfather. I was wondering how yous guys would compare the 357 sig to the 357 mag. Is ammo easy to come by? What are your thoughts on this round in general as well?

    I know around my neck of the woods, .357 sig ammo is available, though the selection is pretty weak. MY LGS only has Remington practice ammo.
    IMHO, the .357sig is not up to the same level as the .357 magnum. Last time I looked, I came away thinking that the .357 sig was in the same ballpark (give or take) as a .38 super. Which isn't bad, actually. But it's not a .357 Mag.
    Some folks really like the .357 sig, but it's not my cup-o-tea.

    I haven't ever used a .357 sig, so I can't tell you much about it. What I CAN tell you is that it was designed to be simular to the .357 mag (I don't think it is quite as powerful though.). A lot of people swear by that round too. :D

    Ive had my G31 for 7 years and i love the caliber. The ballistics that i looked at showed the .357sig to be really similar to the .357mag. As far as ammo, around here you can find fmj ammo all day long at walmart, but for good SD ammo you will need to go to a pawn shop or gun store.

    I have a 357sig. Here's what you need to know:

    Ammo cost- Range ammo is quite expensive...about $20 per 50rds.
    Performance- Good defense round, flat-shooting, capable of very tight grouping.
    Handling- Snappy, very similar feel to a 40sw.

    I think the 357sig is a good defense round and a fun caliber to shoot. But I also think 9mm, 40sw, and 45acp are all far more practical choices if ammo cost is a concern. You can nearly replicate 357sig ballistics with either light weight 40sw or medium weight +P+ 9mm defense ammo, and all the while shoot for significantly less at the range. But you can also pick up a Lone Wolf conversion barrel for a G32 for $120 and shoot 9mm or 40sw out of the same gun.

    In my opinion, if you've shot a 40sw, then you know what a 357sig will feel like. It'll just a group a little tighter and shoot a lighter but faster bullet.

    I have a Glock 32 and am a fan of the round. I also shoot this in a Glock 31, M&P 357 Full-Size and Compact. I like the .357 Sig round and have mostly been revolver guy until recently, so I carried .357 Mag often. I also like .40 S&W, if that matters. I say get the G32.

    I have a .357 sig EFK barrel for my XD.40SC, I like it. Balisticlly from what I've read with 125gr bullets it is within 100fps of the .357 mag. Its more expensive to shoot than more common calibers but its also very unique which I like. There's a reason so many police agencies have adopted this round (its badass). As far as a 9mm equaling its performance - from what I've read even with +p+ ammo which is for me hard to find and no cheaper than .357sig it still doesn't pack as much. And if your going to use +p+ 9mm your really beating the heck out of your gun if your using one of the 9s designed for comfortable carry ie - LC9,Kel Tec PF9 etc some may even discourage the use of +p+ ammo. Again I'm a big fan of fps and for me the .357 sig fits that need well. I wish more manufactures like Kahr would make a pistol in .357 sig that carries well but able to handle the cup pressure the round produces. I think if more varieties were made , the demand would be there and the rounds popularity would surge

    I have a Glock 32 and really enjoy the gun and the round. The 357 SIG with bullets up to 125 gr. is very, very similar to the 357 Mag. The Mag. pulls away with heavier bullets, the SIG just doesn't have the case capacity. The 357Mag's reputation as a great man stopper is based on the 125 gr HP, the SIG with the same weight bullet is right there with it. Ammo is pricy and not the easiest to find but I buy bulk whenever I see it on line or in a store for range work and for carry, I use Double Tap or Hornady Critical Defense.

    What worked for me was making an analogy that guns for me are like shoes for her: "why do you need so many guns" and i'll go: "why do you need 300 pairs of shoes". You can try that!

    In my experience the effectiveness of the .357 Magnum is partially a result of bullet shape and construction. The revolver ammo tends to have a more blunt profile with a voluminous hollow point. The .357 Sig is a supercharged 9mm with a rounder nose and smaller hollow point. While on paper they look very similar, in actuality the Magnum has the upper hand.

    All the 357sig FMJ I've seen has been flat nosed, and I've shot quite a bit of it. Do you mean it's narrower than 9mm near in the upper half of the bullet?

    357sig is fun. I just don't think it offers much to justify the expensive appetite. If someone knows of a good source for affordable 357sig FMJs, I'd love to hear it...I pay $20/box, delivered.

    But here's the 9mm/40sw options I was mentioning, that'll replicate the 357:

    CorBon 40sw: 135gr, 1325fps
    Win Ranger 9mm +P+: 127gr, 1250fps
    "Typical" 357sig JHP: 125gr, 1350fps

    Sorry, I meant to say the Sig round has a rounder nose and smaller HP than the .357 Mag. Even if the nose appears flat, look at the profile. Radiused nose to allow feeding reliability.

    For a defence pistol the 357 sig is just nother choice for you. As a trail/hunting round it falls way short of what a 357mag can do.

    Now all this is interesting and we can discuss energy, stopping power, one stop shots, etc. and on and on but when you really consider everything all of these handgun calibers aren't that far apart. I think bullet placement and shooting until the perp is down is what matters. A caliber with a little more "oomf" may do it quicker but who really knows. Use what you shoot best, feel comfortable with, hit the bad guy where it will do most damage and keep shooting until he stops all aggression.

    One other thing to consider with the .357 sig is its ability to feed reliably. Since its a necked down shouldered cartridge it naturally going to feed more reliably . I'm a big fan of it and my opinions may be biased, but I'm still willing to call it as I se it
