I have an SP101 in .327 fed mag.Those older steel wheelie revolvers...heavy enough to help absorb recoil, yet light enough to still carry comfortably all day long! Shooting standard pressure 158 grain JHP .38's is very comfortable in an SP101...my wife did that for years when she had her .38 SP101!
The best thing about the SP101's and the S&W J-frames, is the variety of grips available that helps make those little revolvers fit just about anyone's hand, comfortably!
It's a sweet shooter, not much recoil, and light enough to carry all day
Only drawbacks right now is ammo availability, but I load for this caliber and have a stock of components and brass.
