    Is it a safe bet that any G23 frame with two pins above the trigger guard will be strong enough to convert to 357Sig ?

    I have a couple of older Gen 2 G23's with two pins above the trigger guard --- serial #'s are ARZ 47X and G648XUS ( w/ ARZ 55X on the slide/bbl) that I would like to convert to 357Sig, but don't want to shoot them loose if they are not good to go for this conversion.

    Any advice welcome, and thanks as always.

    I don't believe your Gen 2's will work, I thought they had to be Gen3 over a certain serial number.

    It is my understanding, that you do not use a frame with serial # before CPU XXX.

    You should not convert either of those G23's to .357SIG.

    Early .40 frames didn't have the metal extensions on the front frame rail insert to stop frame battering, which are necessary to shoot .357SIG.

    G23 frames received these metal extensions in the CPU prefix, G22 frames received these extensions in the CNX prefix.
