The S&W revolver is my favorite revolver mainly because there is a "spot" in the trigger pull where the hammer is all the way back, the cylinder is locked into a loaded cylinder, and just squeezing the trigger another ounce or millimeter or thousands of an inch will allow the hammer to fall.
Jerry Miculek had the S&W custom shop turn a revolver into a gear shifter for his vehicle so he could dry fire when he drives.
My 640-3 is a DA only. I practice trigger pull and keeping the front sight steady often. It has helped me tremendiously. I could tell the difference on every range trip. I only have one gun that you can't dry fire. It's an old Marlin 22 bolt action.
And the OP is right. It does improve the trigger pull by breaking in the surfaces.
It's called staging the trigger. It's in the design. I practice it and am fairly good at it. It makes for a very accurite shot in a DAO revolver "but" is not a fast way to shoot. It takes practice. I like that the S & W can do it. I don't know if other DAO revolvers do? I love my 640!!
I didn't make it up. I've not spoken to or seen any modern firearms instructors who don't recommend dry fire practice.
No, I am well beyond the dryfire argument........ I am now traumatized by the Smith & Wesson shifter knob! Say it isn't really true...... please don't let it be true.
This^^^^If you're worried about damage from dry firing throw a snap cap in. That's what they are made for. A few bucks for a little peace of mind? Sure!
