    Have any of you with Glock 33s bought a Glock 27 barrel to make the 33 a .40 S&W, or is it feasible to even do? I asked a gunsmith I knew and he said it would be o.k. as long as you have the magazine to hold the rounds. Not that I want to, but it sounded interesting.

    Comments would be appreciated.

    All you need is a G27/23 barrel.

    I figure a G33 is the subcompact 357sig version?
    place a .40 in anything other than a full size frame and you will go to flip city.

    I confess having NEVER fired a G33. I would love to because I came to love the round. To me, the 357sig vs the .40cal/sw is like a fine meal versus a bad whopper.

    I understand the reason to play with your weapon. I think it is a great way to grow in shooting. It works for me. But 357-2-40 is the wrong way down a one way street IMO. I WOULD like to fire a G33 though. WOW>>>>>!!!! :snoopy:

    I have a G33 with a Glock .40 cal extra barrel. "Conversion" takes about 10 seconds--just field strip, and put other barrel in. I had the G33 at the range just a few hours ago, and swapped barrels back and forth a couple times. Point of aim and point of impact are the pretty much same at self defense ranges (7-10 yards). I have to say, that G33 is an accurate little pistol. I found the recoil of the .357 to be a little heavier than the .40, and the .357 was definitely noisier for those around me, and a little louder for me than the .40. I would disagree about "flip city" though. It was easy to control and shoot rapid fire. The odd thing is that with Sigs, I found the .40 had slightly more recoil than the .357. With the Glock it's the other way around. Either way, it's not a big difference. Your mileage may vary... Bottom line is pick light/fast or heavy/slow and knock 'em down every time.

    Just curious, can you use the same mags?

    I went in the opposite direction and turned a G27 into a 357 Sig with a KKM barrel. I enjoy shooting 357 Sig (also have the G31 and a Sig P226 in 357) and the 357-barreled G27 is
    my CCW. It's cool having the option of changing calibers with a simple barrel swap. For me, the 357 Sig surpassed .40S&W and it was nice just having to pick up a new barrel to effect the change.

    Usually.
    Some problems were reported with the 10-rounders.

    At any rate, I bought a G33 and a factory G27 barrel. I also bought 2 G27 magazines but that proved to be unnecessary. I've shot Blazer Brass 180, Remington G&W 180 and Ranger T 165 with no issues (Remington is filthy dirty). Softer than 357 Sig, I ususally switch to 40 when my hand gets tired. I'd never carry 40 but it's nice to shoot something so much less expensive than 357.

    The followers in the 357 and 40 mags are different, but they both work with both rounds.

    I have had no issues with using the same mags for both calibers, either.

    I've never had a failure shooting .40S&W out of the G33 357 Sig magazines or shooting 357 Sig out of the .40S&W magazines, so they appear to me to be completely interchangeable. On a side note, I also picked up both a 357 Sig and a .40S&W barrel for my G29, and the 10mm magazines have functioned flawlessly feeding both calibers.
