ditto1958 said:A .357 or a .38 special round will not chamber in the 9mm cylinder. That's the easiest way.
I'm wiping a spot of egg off my chin. Without thinking or checking I said it would drop too far in like a .45 acp in a .45 Colt cylinder. You, of course, are absolutely correct. The tapered 9mm case will only go in about 1/2 way in a 38/357 cylinder. Thanks for the correct information. I'm not bright, but I'm steady.A 9mm won't chamber in the .357 cylinder, either.
