Always read the forum just never needed to make a profile 'till now. I just got a PS90 and I've always had to take apart and clean and study the internals of a new gun. While cleaning the trigger pack in order to wipe down the inside I decided to gut it out and reassemble the trigger pack. Thankfully I didn't completely take everything out. I punched out a pin and then a spring practically stabbed in my hand. I stopped myself and remembered two past experiences (A HK-91 trigger pack disassembly and a browning BAR safari takedown) and thought I better make sure I can get that back in before going farther......two hours later I still can't do it. I can't fid any videos or posts online anywhere with clear instructions or help. A picture is worth a thousand words so here are two.
