we just bought a couple of new Model 41s a 5.5" and a 7" . Since Dry firing is the best way I know of to become familiar with your firearm and get in practice at home without buying ammo and going to the range. Here is what I plan to do.

I will remove the firing pins from both guns and just dry fire to our hearts content.
when I want to hear a Bang I will put the pins back in.

So what is wrong with this approach?
