Ended up selling my last PX4 only because I hated the reset on the trigger. As soon as I found out Langdon Fixed this I went out and bought another PX4 Compact. Although the 1st trigger bar I received was defective, Langdon immediately shipped me a new one and Still giving 5 stars for great Customer support.

Simply great. Take up is almost non existent with the trigger bar and the action is smooth and light with the trigger job in a bag. Not as nice as my ltt centurion with np3 coating, actually no where near as smooth as the 92, but very good non the less.

I would recommend this to anyone who wants to make their PX4 a great shooting handgun.

Is there any chance to exchange it for a S&W M&P Shield .40 cal.

Watched the video (multiple times) and was able to get the install done in around an hour. Once in the end results are fantastic

Just got back from the range. Installed a PX4 trigger in the bag, 11 pound spring with the optimized trigger bar in my 9mm compact. Shot my full size with factory trigger first and had a 4 inch group. Switched to my compact with the new trigger and had a 2 inch group, 7 yards away. Had a range master with me and he also commented on how instantly you could see a difference on the target. I'm not a competition shooter, just hit the range about two or three times a month. It was easy to install. Wish I could attach a pic of my target to the review...
