this is what I'm using right now.
It works beatiful - but you have to glue inside the post or else it will screw away. So in some way its kinda permanent when you glue it. Right now i have to take mine off since I'm redoing my holsters. And its a bitch to come off.
You could buy them here.
Here are some pics of mine on the holsters. you could get any color. brass, black, nickel etc.
I added some leather in the inside of the holsters in order to keep my blasters snug, plus it helps the blaster from getting scratched.
Keep the screws a bit loose in order for your straps to move around. Thats how your holster will stay pointed straight down.
I WILL GO WITH THESE AGAIN. I THINK THEY GO BY THE NAME OF CHICAGO SCREWS TOO.
HOPE THIS HELPS YOU GUYS
