Just what I expected.

Great products. Easy to install. I have slide plates on all my pistols and baseplates on many magazines. I've never been disappointed.

G19 Blacked out USA flag backplate

I’m taking a star off because my backplate had a scratch on it from out the box, I thought it was a hair or something at first but then I noticed it was a scratch. I also thought that the indentations on it would be a little deeper but I’m not complaining about that. Awesome design and product I like that it actually has 50 stars and 13 stripes; just wish that mine wasn’t scratched. Thank you

Hi John,

There definitely should not be any imperfections on your back plate. That is 100% on us and we'll get you a new one ASAP. Can you shoot us an email to with your order number and reference this issue? I'll have the guys get a perfect one sent out immediately, should have been done the first go around but clearly this one slipped through the cracks.
