    Hi. New here - not sure if I’m posting in the right place. Who makes a safe and reliable .357 Sig conversion barrel for the Glock 22? I’m interested in learning of the good or bad experiences of others. Thanks.

    Welcome to the General Glocking forum, the exact proper place for your question.

    An OEM Gen3 G22 with OEM G31 barrel is every single part identical to an OEM Gen3 G31 except:
    -> Fixed rear sight elevation (G22=6.5mm, G31=6.9mm)
    -> Model and caliber markings on the slide's left side.

    If your G22 is Gen4, then there is also a very small difference in the slope of the ejector tip face that may be safely ignored.

    There is no reason to use anything aftermarket. The OEM G31 barrel is $125 once Glock gets over their current virus BS sales shutdown:

    https://store.teamglock.com/barrel-g31-357.html

    All Gen3 and later G22 pistols are Glock sanctioned for an OEM G31 barrel, but very few Gen2 G22 pistols are. Gen2 G22 pistols must be serial CNX###US or later.

    Conversion between 40SW and 357SIG are the ONLY caliber conversions sanctioned by Glock for any of their pistols. Compared to OEM 40SW barrels, OEM 357SIG barrels have tight chambers and perfect 100-percent cartridge case chamber support, even above the feed ramp...all made possible by the bottleneck cartridge design.

    Check out Underwood for very premium ammo and Georgia Arms for reasonably-priced serviceable ammo. Even as good as 40SW itself is, you'll probably seldom be tempted to put the 40SW barrel back in.

    Buy Glock OEM.

    the last time I bought mags in .40 and 357 the followers looked pretty identical. I needed a few dozen mags for our 31s and our dealer didn’t have any so I bought a bunch of 22 mags. No issues.

    I should have specified: Gen 4. The information here is great.

    I'm just the opposite - have a G31 and bought an OEM 40 bbl for it with no other changes. Works perfectly - mags are interchangeable.

    not a 22 but a 23.4, OME 357 Sig barrel for a 32, I have 20 mags for it, only one is marked 357.

    I do run an after market 20 lbs captured RSA in it with the 357 barrel, but that is so I don't have to chase brass into the next county.

    - Is there a similar profile between the 17 and the 22 (in regard to my ability to use this 22 with a 9mm barrel)? If it works, I presume one needs 9mm mags. Thanks.

    Yes, you can shoot 9mm out of your 22, but you have to buy a 9mm conversion bbl, not an OEM 9mm bbl.

    An aftermarket 9mm conversion barrel and 9mm magazines work. But it's a kludge.

    These components differ between a real Gen4 G17 and a Gen4 G22 with aftermarket 9mm conversion barrel even when a 9mm magazine is used:

    1. Slide
    2. Barrel
    3. Firing Pin
    4. Extractor
    5. Spring-loaded Bearing
    6. Ejector in Trigger Mechanism Housing
    7. Recoil Spring Assembly.

    The 9mm conversion is OK for range-toy service.

    The order form from Glock will ask you for your serial number to be assured your pistol will work with the 357sig barrel.
