  1. While its not a design choice I would have made, having that grip safety on the mag well prevent movement of the bolt in either direction from either position does have one unambiguous advantage that Ian hinted at but didn't expound on. It is impossible to charge the weapon while you are thoughtlessly depressing the trigger, because you have to use your firing hand to charge it. While I'm no big fan of support hand grip safeties (because one handed use of the gun in an emergency is absolutely a plausible use case), this is one of the better implementations. I might have beveled the forward end of the rear hole, so one could charge the gun without depressing the grip safety - after all, the normal sear catch would also engage the grip safety post and thus suffice as a drop safety (because the bolt couldn't even cycle far enough to strip a round out of the magazine before the safety hit the sear notch if the bolt bounced on dropping, and thus would act much like the ratcheting top cover for later Uzis).
