Unless you have a secret source of money and ammo, dryfiring is the only way to get really good at double action revolver shooting. Even Jerry Miculek dry fires alot.
I’m Skeert. I busted 2 pins doing that.
I have this SIG/MAUSER 40 SW I was doing that with because the trigger felt like I was pulling my finger through 50 yards of gravel, but I have ceased the exercise.
I suppose I should spring for snap caps.
