    Any benefits/drawbacks to either over the other other than ammo price..?

    I love my G23 and wonder if there is any advantage to getting a G32 barrel for it.

    And from what I can tell the G32 barrel should drop right in and I could use my .40 cal mags too right..?

    Thanks..! :wavey:

    I have a G27 with a G33 barrel/mags.
    Not only is the price different, but also availability of ammo.
    And you get a wider range of load choices with 40.

    Oh, question 2a and 2b.

    2A) G32 barrel should drop right in?
    Yes, the G32 barrel will drop in and work.
    The 40/357 guns (same size) are identical except for mags and barrels

    2B) I could use my .40 cal mags too right..?
    Yes your 40 mags will work - with a caveat.
    For the Range no problemo . For Self Defense ???
    The followers are different with 40 and 357 mags.
    (and maybe the mouth of the mag)
    You can get 357 mags, put 357 followers in the 40 mags, or just run the 40 mags as is.
    The issue is some potential for sporadic FTF.
    Real or imagined - It seems like cheap insurance to just get 357 mags for SD.

    One Final Point:
    I'd love to say I'm super smart and knowledgeable.
    But truth is I got a major education on barrels/mags/followers by fellow GT members.
    Thanks Everybody! Really

    Yep a G32 barrel barrel and .40 mags with work fine with your G23.

    As far as the advantages of one or the other that depends on the individual. For me I prefer the .357sig over the .40 however you may find the opposite.

    Are there better penetration values for either or does either round "hit harder" as the .40s&w is said to do over 9mm..?

    Just OK
    I have a 23 and have in the past been slightly interested in the .357sig. Are there any quick ballistics someone can put up?

  8. My carry is a G23 and I just sold my SigPro .357. Take away the differences in the guns themselves, I found the .357 to be snappier than the .40. I was much more accurate with the .40, though I will tell you that the .357 is much louder and hits VERY hard.

    Practice is obviously the key.

    Only real downside of the .357 is the cost of ammo. Quite high, even by today's standards.

    Well, .357 sig is just a necked down .40 (the case of the .357 is a hair longer) so your choosing between slightly ligher and faster or slightly heavier and slower. The ammo price/availablity/wider range of choices make me stick with the .40.

    I got a G33 barrel for my G27-its fun to shoot. I get inexpensive ammo at Georgia Arms-canned heat and I've never had an issue with it-great range ammo.

    Sell the 23 and purchase a Glock 20 10MM. That way you have the power of an anti-tank weapon that fires a .40 sized bullet. You will be ready to end any alien invasion, slaughter hordes of zombies with one shot, and take down Godzilla.





    I love the .357 round actually and my daily carry is a Glock 32. I also own a Glock 33 and my wife carries a Glock 27. The .357 sig is a fun round to shoot.

    There are a LOT of variables. The .357sig has been known to offer better barrier penetration. But as I said, lot of variables.

    One thing that is nice about the .357sig over .40 is if you load .380 or 9mm you can use those bullets in .357sig also. If your buying factory ammo that don't really matter.

    Dude, why do you (and others like you) have to do this kind of thing? If we asked and answered every question one time, there'd be nothing to talk about. If you're not going to add anything to the discussion, move on to another thread where you're needed.

    Keyword searches on gun forums suck. The OP politely asked, let's be polite and answer.

    If the ammo cost the same, and supply was the same, Id probably get a .357 sig.

    The 115-grain +P+ round has a documented record of stopping felons.

    The above figures should go a long way in explaining why .357sig is not a 9mm bullet on steriods, anymore than .357 Magnum is a .38 Special on steroids.

    Thank you.


    One more benefit of the .357SIG that I have found versus both my G22, and a since departed P226, and current P229R: Whatever group it's shooting in .40, can pretty much at least cut that in half with the .357SIG. Whatever the .40 was shooting at 25 yards, the .357 ends up doing it at 50 yards. Might be irrelevant in the grand scheme of things. Just the results of a resident .357 honk fanboy homer. Yeah, I know...it's just a 9mm on steroids. But nobody cared what Mark McGwire and Sammy Sosa were doing off steroids. :v D

    Really performance is the same. It is a matter a of style. If you want to look hip in the gun carrying world you have to go with the 357sig. It says, "here is a man who knows what the crap he is doing".

    On the other hand, if you see yourself more of the chubby night watchman sort of guy, well then the 40 will say as much about you as the dounut roll of flesh rolling over your belt.

    Wow the crap is getting deep in here ^^.


    I've picked up another 357 sig as I'm planning to start reloading it again. My problem with it has always been an ammo shortage or expense. Reloading is great but the necked case is a bit frustrating at first. I am looking forward to re-learning it. Wishing I had never dropped it now TBH or maybe I'm just bored and want to play around with it again.

    I like it but I've never jumped on the band wagon of all these rediculous claims people on forums often make. It's just brass, lead, and powder to me.:supergrin:

    Since when have cartridges been accurate rather than the gun? Kinda putting the cart before the horse I'd say. Unless there is something inherently wrong with the design of a cartridge such as the original 38 super which would headspace on the semi-rim.

    I've never gotten better accuracy with 357 than .40 with factory loads nor my reloads but then, I wasn't expecting to. Maybe if I had been expecting it I would have gotten it?

    From my experience loading .40/357 the real difference in ballistics is ( mr. obvious here:supergrin:) the size and weight of the bullet. In fact it's possible to equalize one of those variables by loading similar bullet weights to the same velocities. I just see them as far more alike than different. That is why I dropped the 357 the first time. I loaded from powder puff loads to nearly max and it was like, for all my effort I was loading the same cartridge twice.

    IMHO It comes down to personal choice. I know that is the standard boring anwer.:whistling:
