I have the pro .45 model and i have only put about 150 maybe 200 rounds through it. The only dismantling i have done is removing the slide and doing a lite cleaning/oil and grease. Put it back together and it sat for about a week. Went to shoot it yesterday and everything felt fine but after a full trigger pull...nothing. you can hear the click of the firing pin and it still leaves a small indent in the center of the primer. I need hwll figuring out why the firing pin is not hitting the primer hard enough or not traveling forward enough......PLEASE HELP ME!!!
