About the .38 S&W - .38 Colt New Police - .380-200:
Yes, dimensionally different than the other .38's (none of which are actually .38 caliber - didn't see that anyone mentioned that - some are .356. most are .357-.358). The .38 S&W is .361". It will not fit in many guns chambered for the .38 S&W Special.
