I supposedly have the newest gen ATP, blacked out trades glock style trigger I was running propane with kwa silicone oil in it and high quality .25 bbs same as I use in my PTW. I started out with the mag that comes with it in the weapon 2 new mags in pouch. The mag that comes with the gun would barely move the slide and get any range for the first 3-5 shots but then it would seem to act normal almost as if the mag had to warm up to being used. The other mags work fine. After a heavy day of use, about 8 full mags threw it at the end of the day the other mags seemed to do the same. Although one mag would seem to put some hot shots out for the first shots then slow down and be kinda hit or miss. I followed the videos you guys pointed out for proper cleaning and lubing that ATP so Im not sure what to check. Is there a break in period on this model? I have had loads of other KWA gbb pistols and never had an issue like this. Granted the first gen of ATP I had was crap and it had all the issues under the sun that an ATP could have just want to see if theres a spring or different way I should look at this issue. Love the pistol though was reliable up until the point of crapping out. My thoughts were it just got used and dirty when I brought it home and cleaned it I did see alot of that grey lube so I think that might be it. Any help would be awesome.

I have stippled, filed out a little of the mag well to aid in reloading(found the mags tended to catch on the flat part on the front so I smoothed and rounded that) dremiled a notch on the trigger guard so I get the same hold on it all the time, also cut a curve out of the sides of the bottom of the mag well I noticed with some minor sand the mags didnt pull free some of the times so this just aids in that. Heres some pics

Hey adamasatp,

I'm sorry to hear that you are having issues with your ATP.  But I would need to know some other conditions just to help eliminate possible issues.  About how warm was the weather where you are shooting?  I ask this because I was having cycling issues with my ATP, but I soon realized that this was mainly because of over pressurization of my magazines.  In the morning my pistol worked fine, but as the day got warmer and hotter the pressure in the mag caused my pistol to light strike and not cycle, this was resolved by simply releasing some gas and it started working again.  If this doesnt solve your problem, please contact our help desk and one of our customer service representatives can help you.

The poster also indicated that he used propane, so he would also have had a naturally higher PSI value versus green gas.

I have also experienced the same issues with over pressurization of the mags from excessive heat and using KWA Green Gas. A little embarrassing when I was doing a product demo for some LE guys from LAPD metro this past weekend. A simple way to test if this is the same issue is to grab your mags in their natural unheated temperatures, gas them up and then test how they cycle. If they cycle fine, then the over pressurization when the mags are over heated is the most likely cause.

It was a good lesson learned: keep the mags at room temperature/cool or at least covered in shade before doing any product demos. If using it at a game, try to keep them covered up in a pouch if possible.

Did some cleaning and all and tried to make sure I dont over fill the mags and she seems to be doing fine. Just got in something to hold the ATP Safariland makes some good gear but I hate the stock leg panel cant wait for the replacement to arrive.

about the over filling of mags, (especialy because you use propane like me), if your the kinda guy who doesnt use the pistol alot while you play, its more of an emergency thing, the extra psi in propane will expand and make the atp go nuts. it will have striking problems, or dump all the gas. to avoid this on warm days, dont top off the mags, or fill them and let a little gas out. also keep the hammer lubricated. most of my shooting problems have come of a dry hammer mech.


on another note, i love your atp. looks GREAT.
