Hi,
Normally I prefer blue to SS, but a stainless 4" GP is still on my wish list. I have its little brother, the 3" in blue, so I guess variety is good?
You'll probably get lots of opinions on GP triggers: should they be worked on, have different springs, etc.? My own experience is the more they're shot, the better they work. Lots of folks, myself included, like to put 'em thru an extended dry fire session to help out. That, too, is an arguable practice!
What I do know is a buddy who's a Smiff guy is always amazed at how good the trigger on my GP feels. "Come on, tell me the truth: you've had it worked on!" Nope... just shot a fair amount, and dry fired more.
On the new grips, two friends have the 4" w/ the new grips. Only concern I have is the HKS speedloaders that work well w/ my "old style grip" 3" hang up a bit on the new grip. One can carefully relieve the grip w/ a sharp blade, or perhaps a different brand speedloader would work better?
Good luck!
