Hello Again,
To give you more info in choosing, I have:
.22 S&W Airlite 2" BBL, as previously mentioned
.38 +P S&W Airlite Ti, 3.2" BBL Shoots Great, I love it.
.38 +P Taurus 85, Alum Frame, Stainless Cylinder,2" BBL, with the Crimson Trace Laser Grip- Shoots great I like it very much +.
.357 Taurus Titanium 2" Ported BBL, 7 shot. Sitting here at my keyboard i MIGHT be able to shoot my 15" Monitor. This is with several .357 Mag loads, several .38+P loads, and std .38's.
It Sucks. However not bad enough to stop me from buying:
.357 Taurus Titanium Tracker with 4" BBL. Shoots great I love it.
For carrying weight in a backback vs. power, I think the S&W .38 shooting HOT +P's, is more than enough for defense. With std .38 loads rabbits and such are easy meat.
If you do want to stick with the .22, go with a 3" BBl and adjustable sights on the S&W. At 12(?)Oz. it is superb, but costly.
Good Luck
