No harm, no foul. You did give five options; so which five guns would you shoot that nice ammo selection out of?
1. (.22 long rifle) 1957 .22 Combat Masterpiece (I hate the "Pre-" designations) - owned, Passed down from Granddad, still works just fine!
2. (.38 Spl) Model 64 DAO 4" M&P - owned (Brand new to me, just put 200 rounds through it yesterday while waiting for my daughter to get out of class. Thoroughly rekindled my love for the often maligned .38 special cartridge and the incredible S&W Double-Action trigger pull.)
3. (.44Spl) Old Style Ruger Vaquero, 7 1/2" bbl, SA .44mag - (owned, so that's what I use. I wish I'd kept a Taurus {I know, I know...} Stainless Snubby in .44 special that I used to own, I loved that gun, just didn't realize how much at the time. If I had throw-around cash today, I'd look for a 4" Model 29 to shoot .44 specials out of, but with the cost of ammunition, and the fact that I've already got a gun that will fire that caliber, I don't see that one happening.)
4. (.45 Colt) SAA clone, 4 5/8" bbl. - (owned, never could afford the real thing, but this works just fine for my purposes...sending tin-can and milk carton desperadoes to their spot on Boot Hill. My wrists won't take the recoil of the .44mag anymore, but the BOOM-push of the .44spl and .45 colt are still addictive to me.
5. (.45 ACP)...Don't have a revolver that shoots these things and honestly, I don't want one..don't have the patience or dexterity to fiddle with moon-clip thingy's all afternoon. Shooting's supposed to be relaxing, so I'll just stick with my SW1911 for this caliber and be happy about it.
