    I am considering adding a G32 to my collection, possibly for carry, and curious regarding the "better supported chamber" of 357 Glocks. I'm already sold on the merits of this caliber. I previously owned a G32, but it was in the early stages of this model, plus I have developed my knowledge base and shooting skills substantially since I sold the gun in favor of shooting 9mm's. For the record, I do not/will not shoot reloads or lead. For carry I'm using only high-quality ammo from Speer, Remington, or Pro-Load; target ammo from GA Arms, Winchester, etc.

    I have searched/browsed/read the GT forum, in addition to various web sites that I believe are somewhat reliable. I understand why Glock chambers are the way they are for feed reliability, as is the case with many semi-auto's. However, is it true that Glock engineers have designed a better supported (but not fully supported) and tighter chamber for the 31/32/33 vs. their .40/.45/10mm offerings? A particular writer stated that the Glock 357's even offered better support than the G19 (of which I own a pair). I've field-stripped a G19, looking at the loaded chamber with a Speer GD 124gr +P, which appears to be nearly fully supported except for slight exposure at the 6 o'clock position over the feed ramp.

    Can anyone verify the statement regarding Glock 357 chambers being tighter and more supportive than the .40/.45/10mm, or even 9mm models? Would anyone have a pic available to validate this?

    Thanks

    If you take a 32 and 23 barrel and place them side by side you will see a big difference in the support area mainly around the 6 oclock position.

    Take a trip to you're gun store and have the sales person show you the chambers areas.

    The support is greater in the 357sig vrs other calibers and if I would rank it for stock glocks the order would be;

    9mm
    10mm/357sig tied
    40sw
    45acp

    Yep my 45 has the biggest un-supported chambers area. Do I worry about it ? NO. I shoot factory loads, ensure that my re-loads are in warm to mild and use good handloading practice.

    The .357 glocks are at least as good if not better than the 9mm in terms of support.

    I just got an aftermarket barrel for my G22 in a 357 sig flavor. One of the first things I checked before even putting it in the gun was how the chamber was supported vs. my 40 S&W barrel. There is a fairly good section of the case exposed on the 40 S&W but on the aftermarket barrel the metal to metal contact at the 6 o'clock position stops right where the case starts to bevel in for the rim. I have not had a chance to shoot more than about 40 or 50 rounds with it but as of yet I have not had any feeding problems.
    The only problem I encountered was one misfire. I am not too concerned about that yet as the entire gun is fairly new with probably less than 300 rounds from both barrels. I would still consider that a break in period from the number of rounds I have heard others have shot through their Glock's.

    Compared side by side with my G26, the G33 is better supported. In fact, I would venture to say it is fully supported, as I can't see how it could be any more supported.

    Thanks to everyone for the responses. I'll probably be joining the club in a month or so, beginning with the G32.

    A welcome to the club;)

    You may want to look at all these pistols before you decide on one.
    These are all about the same size.

    Thanks, Screaming. I'm pretty much a Glock person but I would consider the SIG. My holsters, etc. are for compact and sub-compact Glocks, so another reason to keep it simple. And Glocks are the only handgun I've owned since 1991.

    That is correct.
