I purchased a PM7 two days ago and have yet to shoot a ball through it. I took out the trigger spring for a lighter pull and it was great for about 4 minutes until the trigger started sticking bad. Now I have to physically push the trigger back forward it sticks so bad. I have no idea what is causing this. It cant be dirt because its only two days old and has yet to be even taken outside. Any help as to how to fix this would be appreciated.
P.S. - If there is a thread on this already I am sorry, but apparently the search feature is disabled when there are over 1500 people online, which is just about always it seems like.
This happend to me as well but mine was getting stuck on the solenoid it was getting stuck on the microswitch itself a little bit. You can either sand a VERY SMALL amount, just a couple rubs off of that nub so it wont stick to it. All i did to fix mine was mess around with the adjustment screws and it start to work. I would use the sanding as a "last resort".
Cut the spring into half and take one of the adjustment screws and replace it with the upper left grip screw ( if your barrel is pointing to the left). Then you can freely adjust the trigger with no trigger stick without taking off the frame (Just like the DM5).
