I've never had a jam in a semi that could not be fixed by racking the slide again. Never had a jam in my glocks at all. I've had jams in 2 revolvers (a .22 and a .357) that totally siezed the cylinder. It took a lot of fiddleing to free those revolvers. Good thing my life did not depend on those guns at that moment. That being said I have a .38 that has functioned flawlessly so far, I carry it quite a bit.
If you can't be trusted w/o an external safety on a dao pistol then you probably shouldn't be trusted with a gun anyway.
