    I know alot of barrels fit different models, but then you have the extractor, ejector and mag nuances. I am not interested in all that. I want the same reliability between barrels.

    Is it basically .40 cal to .357 sig, and even then, are the mags, extractors and ejectors 100%?

    .357 sig to .40 was a factory option, I had a G31 that came factory with both barrels. Either caliber runs 100%. No other calibers are 100% without swapping other parts, but many like the .45 ACP to 10mm and the .40 to 9mm are darn close with the right mags.

    I like my G35 with 357 and 9mm barrels, and of course, the 40.

    My understanding is that generally speaking most Glock 40/357
    guns are identical except for barrels and mags.
    Same ejector, same recoil assembly; same, same, same...

    In simple terms - a 357 Sig is basically just a necked down 40.

    The only difference between a .40 Glock and a .357 Glock are obviously the bores of the barrels, and the magazines. The magazine tubes themselves, and the followers are different. Most people report having no problems using either magazine for both calibers though, just be careful not to accidentally load the wrong caliber into the wrong barrel.

    All you have to do to convert a .40 Glock or a .357 Glock to the other caliber is to drop in a barrel from the same sized model of the other caliber.

    However you shouldn't shoot .357SIG through a .40 frame if that .40 frame is before the serial number prefix CNX for G22 frames, or before CPU for G23 frames. Those frames don't have the added reinforcement to the front frame rail insert to stop frame battering.

    I'm going to say .40 and .357. I'm going to get the .357 barrel for my 23 (soon as I get it) I'll probably shoot the .40 mostly but would like the option of shooting the .357 if the need should arise. I'm not sure yet which brand barrel but I'm leaning toward LWD.

    The 10mm to .40sw conversion works perfect with just a barrel swap...

    Model 35 here with a LoneWolf 40-9 barrel. Short of using 9mm magazines from my 17, haven't done anything else. At least 7000 rounds through it without a jam using anything from Walmart stuff to reloads. Maybe just lucky but........ it's been great. I purchased a .22LR conversion kit for it and its been awesome also.

    Agreed. I've been running 40-9 conversion barrels for years and have never had to change an extractor or ejector. Doesn't mean you will have the same experience, but it sure tips the odds in your favor.
