We mill every part — we don't print them, etch the surface, or order them finished from overseas. Engraving gets cut deep into the metal, so it doesn't wash out after a few years of carry. Brass costs more than zinc. That's the point. A brass piece feels different in your hand, and it'll outlast the gun it's on. We'll tell you up front what a part will and won't do — cheaper for everyone than finding out later.A back plate is small. That's why it works. Rank, MOS, service dates, a branch crest, a kid's name, a buddy's retirement — engrave what matters and the slide carries it quietly. No speech required. Send us text, a logo, or a photo of someone's actual handwriting. We'll cut it. Most of what we ship is bought for someone else — a father, a son's first carry gun, a friend heading out.
