    Yep! You may want to pick up a couple G33 magazines, as the followers are slightly different and feeding issues could happen. If it's a range gun just use The G27 mags.

    Thanks for the reply. Thinking on giving it a try.
    I think you'll like the .357 sig. I have a Glock 32 and 33 (subcompact) and I think the 33 is going to be my EDC. Personally I think the .357 has less hand smack than the .40. And who wouldn't be pleased with a 125gr Speer Gold Dot bullet moving along at 1350 or so fps. (Underwood Gold Dot loading does 1500 fps out of a 32 so you can figure about 1450 from the 33/27. That's .357 Mag power.)

    Yup...for EDC purposes, the .357 SIG follower is different and is more reliable in terms of feeding that particular round!

    It's a fantastic little round...very fast...very accurate...has a fairly 'flat' trajectory...and doesn't hit as hard in the hand as .40 S&W does!
    Most manufacturers of .357 SIG make a 125 grain round, but Hornady makes a 135 grain round and a 147 grain round.

    Well tried it today impressed with the .357 sig. Glock 33 barrel dropped right in the 27. Mags are different but both 33 and 27 function fine.

    Nice...and Congrats! I have it set up just the opposite way in that I have an extra .40 S&W barrel for my Glock 33 .357 SIG pistol!
    The .357 SIG caliber really makes that .355 diameter (aka, a 9mm round) perform the way it should...with the 'umph' behind it to really drive it...just like the effect a .357 Magnum round has with a .38 caliber bullet.
    Just an FYI...you can also get a Glock 9mm conversion barrel for it and shoot 9mm through the same pistol...but you'll need a 9mm magazine for it to make it work...but lots cheaper shooting!

    Along with a 357sig barrel I also bought a Storm Lake 9mm conversion barrel for my G27. Shot 2 boxes of 9mm ammo through it using the G27 mag, had 2 FTF with Wolf ammo, no FTE's. Have since used G26 mags. Haven't had any FTF of FTE in the 200rnds I've shot since.
