Ok, I am not a 1911 guru by any means but I do have some range time on a few of them. I am interested in the Springfield line of 1911's because of the price and quality. My question is do the Mil-Spec versions that are built to look like the WWII versions have all of the modern safeties on them, particulary firing pin block? I know that some earlier 1911's didn't have firing pin blocks and if dropped on the muzzle they could go off. Do the modern Mil-Spec Springfields have these? I really love the nostalgic feel and look to these and I would like to make one of these my first 1911 some day. School me 1911 gurus.
