Links to walther pps m2 trigger

[gassprint1]

My pps m2 trigger is feeling pretty heavy. When shooting over the weekend, if i slowly squeezed the trigger, it felt really hard and you couldn't feel it break at all. If i squeezed trigger faster, it still was heavy but not as hard. I want to disassemble and polish up the trigger assembly like i did on a marlin 60 years back. It shoots great but it doesn't come close to the trigger on my px4 storm or sr1911. I have the skill to do the work, but taking apart is a bit foreign being the components aren't exposed as a rifle or such is.
Anyone know of complete videos removing the trigger assembly??

Nevermind. Sending it to walther for the striker assembly to be checked. The spring is binding pretty good causing a heavy trigger.
