I never use safeties..

My mauser the safety wont go on with the scope on, It has a position I can cycle the action tho.

The Mosin I don't have a safety ( Unless I manually drop the cocking piece )

The Cooey no safety, only de cock it.

My single action no safety, just position of the hammer.

My Single shot shotgun, no safety just hammer position.

My 1911s are the only one I use the safety, when shooting matches I have a loaded gun.

Then again I dont trust no mechanical safety but my own.
