When I am chamber checking a new round of handloads or I am checking feeding ability of a new to me magazine or one where I have adjusted feed lips, I will use the manual hammer block safety for safe handling with live ammo at home.

I am not of the camp that the safety should be willfully and purposely used for dry fire. I don’t on my 52’s or my 745’s or any of my single action only true PC Limited target pistols.

It’s my position that the hammer was purposely designed to smack the firing pin and NOT that safety drum. And a firing pin is easier to source and replace than that safety unit is.

I do all my dry firing with the safety off.
