While adding a suppressor might "work" or at least help some, (it would also reduct muzzle flip considerably) I didn't really see that as a great solution - that's a lot of money to throw at a problem that should probably be addressed in other ways.Prolly helps that the can adds some weight to the gun, reducing recoil a bit.My wife had this problem... awesome with a .22LR, but crap with the .40. I tried everything (coaching, snap caps, mixed snap caps and live rounds, etc.), but the flinching remained. Then I found the cure-all: a suppressor. Throw a can on the gun and she turns into freaking Annie Oakley. Turns out she was just scared of gun's report. Once we tamed that and she felt how little the recoil really was, the problem evaporated.
