Here's a before and after I did for a friend's ATP who liked the stipple work I did on my other one:
Pics of my personal piece:
One of my ATPs with OTG Glock holster and Glock mag pouch:
Worth noting, while this is a Glock holster, I have since discovered that holsters made for the S&amp;W M&amp;P 9mm are a perfect fit for the ATP. Perfect draw. Perfect retention. Not too tight. They're just right. Tested this in my various M&amp;P kydex holsters including Raven Concealment, Kaluban Cloak/Griffon Industries, OTG, Spada Holsters. Worth mentioning, OTG now makes kydex mag pouches for airsoft Glock mags. They account for the slightly taller airsoft BB feedlips and are universally compatible with KSC/KWA/TM/HK3P/WE Glock mags. The above picture is for RS Glock mags, hence why the fit isn't perfect.
I've stippled the frame and mag base pad for better gun manipulation control. Also added some rubber grip tape to the rear of the slide: I've always been taught when reholstering (Glock's, M&amp;P's etc) you should have your thumb at the back of the slide pushing it forwards to ensure that the slide remains in battery. The rubber grip tape works as an index point and prevent your thumb from slipping in wet conditions.
Since taking these pics I've blacked out the engravings on the slide (masked off the slide only exposing the sides and a few quick and light layers of Krylon Matte Black).
My gun gets pretty dirty during some practice games. Going urban prone a few times with the ATP in my holster on my hip. By the end of the day, the gun was basically unusable from all the dirt. But that was all me. Took the time to clean up my ATP (one thing I love about cleaning airsoft guns ... no carbon to clean up). Used gun cleaner followed by some EWL for lube. Will probably use GHK silcone oil in the future once I get some.
Did a couple other quick upgrades. The first was installing a KM tight bore barrel I picked up during my last trip to HK. The second was installing some Nitesiters.
This video is really just to illustrate the effectiveness of Nitesiters. They're not a replacement for Tritium Night Sights (like on my S&amp;W M&amp;P), and you do have to charge them up briefly with a bright flashlight or UV flashlight, but they're brighter and stay bright longer than most other options such as glow paint, etc.
For just $12, you get 8 Nitesiter dots. They're easy to apply (come with simple instructions and everything you need). The Nitesiter dots fit perfectly into the recesses of the white dots of the irons. On some guns I have had to add super glue around the edge of the dot (something they recommend if you have problems with the dots coming off), but I suspect I won't have to since these Nitesiters sit really deeply in the recesses.
Sadly the KM tightbore barrel didn't appear to improve accuracy or range.
Overall really happy with this gun so far.
