Mine is butt ugly and shoots great. The mags all had leaking problems, most of which I've been able to fix with teflon tape, new orings, new valves, and some lube. It's very very typical for a KJW piece.
What Knief said is about right. Due to the paint on it, it doesn't have the best looks. Regardless, the gun works great. It is a very accurate and a solid sidearm. Main problem is the mags, but are fixed quite easily.
Airsoft isn't about being the fastest guy on the field, a guy with 99and1 kill ratio, or a being the dude with 1000's of dollars worth of guns and equipment on the field. It's all about having fun shooting other dudes who want to shoot you.
I did this to my kjw 226 pistol mags and all of my WE m4 green gas mags. And it works great. But don't over do it, otherwise it will flake a little and come up through the mag discharge valve. It then gets trapped in your inner barrel and can lead to problems.
