I have installed a match trigger kit in my bb date code usp45 and have fired a couple hundred rounds since the install. On occassion the hammer falls to the deckocked position while firing, about once every two mags. pull the trigger and it goes bang, no problem, just expect it to be in single action. My thumbs are held low to make sure I am not decocking unintentionally. The single action trigger pull is very light, 2-3#, as the kit came from HK. All of the parts were installed without issue, using the hk parts plyers on the trs makes that one. Any suggestions on what causes this to occur?
