    Sorry I may have over thought my original reply. If you got a Glock 27 already and you want the .357sig it is defiantly cheaper to do the conversion barrel and utilize the .357sig mags (Glock 33 or the larger 32 or 31magazines for larger capacity reloads or range fun) than to purchase a whole new G33. Like I said you can use the G27 mags but if your carrying for CCW I personally would carry the G33 mags for ultimate in reliability. Of course if your just have to much money and you can't still decided then just purchase a G33 and have some fun

    using .40 mags for .357sig

    The 40 mags do fine until the final round which tends to stick. i solved this by finding a Glock guy at a gun show and buying "3" .357 sig mags and received a discount for buying three. Also you can order .357 sig ammo for cheap at Georgia Arms online website. Thanks

    Really...I would thought it would have more recoil...

    Friend has completed this with no issues..I have been thinking about converting mine....But then again I have a Stainless Warthog I also carry.

    Plenty of ammo out there, especially online. My favorite is Double Tap. The Gold Dots aren't that much more expensive than any other premium ammo, yet toss a 125gr Gold Dot out of the barrel at 1450fps and a 147gr GD at 1250. Very impressive loads! I've been finding JHP's at several WalMarts.
    actually .357SIG is made from its very own brass. since overall length of the brass in the finished case is the same as .40S&W, the case has to be slightly longer than .40 prior to the neck-down operation, otherwise it will be slightly short after the necking operation. you CAN reload .357SIG using .40 brass, but it will be slightly shorter than original SIG brass. and it's not necked down 10mm brass either, because 10mm uses a large pistol primer, while SIG brass uses small pistol primers.

    You guys revived a thread that was over 3 years old......

    I shoot .357 sig out of my .40 mags all the time with no problem.
    Stop whining and go do something that makes a difference!
    If you think that I may be talking to you, then I am.

    More people are turning to the .357 SIG each day.

    It's a great cartridge and the Glock 33 or a converted Glock are great guns.

    Plenty of guys have made the conversion work with the G27 and even bigger .40s, but I don't know about having to have specific mags.

    Personally..I'd buy the 357 mags myself.

    Minimal cost to avoid possible major headache.

    You might be like me and have owned a few .40s or still do.

    Once you go .357 SIG- you might wonder why you bought those 40s?

    Best of luck with your conversion and entry into the world of the .357 SIG.
