Double Diamond GOLD AMAZING Barrel

by

Double Diamond barrel I bought for the Glock 47….
Glock 17 threaded barrel.
Glock 19 recoil spring.
Fit perfect and is amazing.
I am ordering one for my RxM. I already have the heavy weight recoil spring and it fits amazing as well.
Oh and the extended slide release is a must
Black slide gold barrel make me feel like royalty.
Might have to order a black barrel.
Compared to others in the market this barrel blows them all out of the water.
Smooth and silky the threads are perfect.
Wouldn’t trust another brand for my suppressor.
Arrived packaged very well. My other from another company came with smooshed threads.
Just the tip.
