The only striker-fired pistol I've ever carried is an H&K P7. It is always uncocked until the cocking lever is squeezed. Release the cocking lever, and the gun is uncocked.
I would never carry a Glock in any condition or in any circumstance. The only semi-auto pistol that I currently own that I would carry is a S&W Model 39. Other than that, it's my J-frame hammerless.
