I bought some hornady Tap rounds for my Glock .40 and while they look cool and all pretty i went to do some dry practice and while i was clearing the gun to take it into the other room i kept feeling really paranoid that there was still a round in it because of the black casing. i know that you all might think i'm over reacting but it made me a little nervous i checked my gun like 3 or 4 times before i put an empty mag in to do my dry practice. It just made me a little nervous. not a big deal just something to think about. i feel alot more comfortable if on the visual check of the chamber and mag i see brass or no brass.
