"I have a 360PD and when I first shot it with the original grips it had a tendency to snap causing the trigger guard to hit the trigger finger causing a painful situation. ..."
Yes, that 'situation' is called a cut trigger finger for me.
After putting new grips on the gun, I want to try more ammunition. Dry firing the gun extensively, the 360PD is now locked up tight as a drum, with a cylinder that won't open, and a gun that won't cock. 100 rounds, and a ton of dry firing on empty cases, and the gun locks up????
I'm going to find out if this is due to the lock, prior to having S&W, or my local gunsmith fix it.
Others have suggested pulling the locking mech on these guns, and, I said it would never happen to me, so, I'll leave it alone.
I'm having serious second thoughts about it, and, I may ask S&W for a full refund, since I consider a SD firearm, with a lock that can make the gun not function, unfit for it's intended purpose, voiding the 'Implied Warranty' that the firearm is suited for it's intended purpose...
