I'll cheat and go with a recent poster's "function" comment:
Fun
Ruger Single Six "Vaquerito"
- .32 H&R Mag
- Single Action
- 4-5/8" bbl
- Blue
- Most hoot to shoot and my first handgun ('84)--in 5.5" adj sight form--that wasn't a family hand-down piece. One of best pairings of cartridge and gun I've ever run across - tied perhaps with .44 Special mid-frame (SAA/Ruger).
Self Defense/Carry
S&W Lady Smith 65 pre-lock
- .357
- Double Action
- 3" bbl, full lug
- Satin stainless
- Most all 'round useful; carryable power. Fifteen years or so after S&W discontinued, still the "perfect modern DA," IMO.
"Indefinable" (combo of features)
Ruger New Vaquero "Sheriff"
- .44 Special
- Single Action
- 3.75" bbl
- Bright gloss stainless
Most flexible caliber for what I need, .357 usefulness without the "sturm und drang," decent power for just about anything south of 45th parallel, a sort of "Doc Holliday" charm, harkens to old west but utterly reliable, actually carryable. Loaded "hot" for black bear country and snakeshot for the no-leggeds, just about covers it all as the ultimate camp or trail gun in my neck o' woods.
"Just because"
Cimarron Model P
- .44 Special
- Single Action
- 5.5" bbl
- Antiqued (non factory)
- My most "fondled" handgun. Tuned to high heaven, perfect balance, classic 4-click snick-snick feel w/o worrying about nicking it up unlike my similar configuration recent-year Colt.
"Had to choose" (not even listed above)
Ruger New Vaquero
- .44 Special
- Single Action
- 4-5/8" bbl
- blue
Most practical combination of above features (plus) that still has an "emotional" component making you want to regularly handle it. Perfect/most useful overall barrel length. Harkens to "old west" charm but fires full six. Needs to be CCH'd to complete and really "speak to me" but it's a great package as it is.
"No, really have to choose"
- Above S&W 65 Lady Smith. Not my emotional choice (see immediately above), but the one I probably would have to pick. Darn close to the perfect daily-use handgun if hunting (optimally) isn't on the list.
