Tam on Dry Firing (emphasis added) …

As a matter of fact, my daily routine over a period of several years was to dry-fire my pocket J-frame, at first a 442 and then a 432, fifty times as rapidly as possible with each hand and then, while my fingers were good and worn out, try to hold the dot from the laser steady on the backstop through the normal double action pull. Now, both these guns had the newer frame-mounted firing pin, but still… Call that 150 dry snaps a night, pretty much every night, for a five year stretch, and you have a wheelgun that has been dry-fired well over a hundred thousand times.

I dry fire every gun I own and won’t buy a gun I cannot dry fire.
