It should be no secret that I am a fan of customizing and personalizing weapons. You own it, so you should make it uniquely yours.
Jackrabbit Designs (out of Waxahachie, TX) is now offering custom laser engraving of, well, anything you want to send them. They can do it on grips that they sell, or you can send in your own grips, holsters, pretty much anything that is not serialized–they are not an FFL so they cannot accept components that category. That said I don’t know if it would change if you were local and could wait while they did it–I have no idea how long it takes them. I’m pretty sure you could certainly send in an 80% lower…
They can engrave nearly anything you want. They have art, or you can send in logos, department artwork, etc. Get your initials cut in. Have some identifying information cut in to deter theft. Make it yours!
