None of the above. Years ago, like 20 years ago, I owned two of the Charter Arms Bulldog and Bulldog Pug revolvers. They were fine. My friend just bought a new one, stainless, it is okay thus far. They are not good pocket guns. They are too big and too heavy when loaded for pants pocket duty and they are not built heavy enough for my taste.
327 Federal ... if they say so. Give me a D frame Colt or J frame Smith any day, in 38spl, of course! On the 327 Federal, I would be wary of firing it indoors with a short barreled gun. Permanent hearing loss seems likely. 38spl won't have that issue. I have done it. 45ACP is also forgiving indoors where at 357 Magnum will seriously damage hearing.
