Really cool gun, but the handle destroys the great look.
If you want better aesthetics, get rid of it or make it a lot better.
Oh, and the cleanout cap in the back of the gun isn't pressure rated. Find a threaded plug that says NSF-pw on it.

I have a bunch of 3/8 qevs so maybe i will try one but it vents just fine there is only 3/8 of an inch movement of the piston and the rest of the area is filled with a huge thick rubber washer.

Did you use an airbrush or just spray paint for the sprayjob? Those colours are cool.
