Sorry, I think we're talking past each other. I'm not referring to the magazine disconnect safety, which has always been on the P35. I'm referring to the firing pin safety that only appears on MkIII guns.The manual of arms is at least as important to me: accustomed clearing a pistol; aiming at the target and a final trigger press before removing from the line. If only for my own use, I'd be willing to disable the M.D. ... but not for student use. Not because less safe: because lawyers.
