Thanks.
If you want a colored frame glock, they made them in OD green like my 23 up there, and flat dark earth (tan). The colored frame versions are a little more expensive because there are way more all black ones, so people selling the colored frames think they have some sort of special collectors item..
If you wanna paint the whole gun, I would suggest the oven cure Cerakote over Duracoat.
Or you could just use some vintage krylon and get all hip hop on it, haha.
