Just installed the Trigger Job in a Bag. It took about 5 minutes to do the install, glad I didn't pay someone to do the job. All I can say is wow. I don't have a trigger scale so I can't say what the pull changed. It is however much smoother and lighter. Can't wait to get to the range.

I was able to purchase the PX4 Compact from a local gun store on Beretta Blue Label (I am retired military) for a good price. The stock trigger was okay, but I had the PX4 Carry from Langdon and had seen the difference between the stock trigger and the LTT Trigger. As a result I elected to purchase and install the trigger job in a bag with the Langdon Optimized trigger bar. The installation was straight forward, no special tools or skills needed. The difference in the feel of the trigger compared to the stock trigger was night and day. It was so good I chose to invest in the Optimized trigger bar for my LTT PX4 Carry which I had purchased without the optimized trigger bar. The Double Action pull is so smooth (7.5 lb) on both that I do much of my shooting DA in order to improve my trigger control and discipline. I cannot give a higher recommendation to this item. It was worth every penny.

Much easier and quicker installation than anticipated thanks to the video, and improved all aspects of what was already a nice (but heavy and stacking) stock trigger pull on a vanilla PX4 Compact. I went with the 12 pound hammer spring as I do like some resistance (not a competition gun). SA is way lighter, while DA is smoother and a bit lighter but still feels very safe for carry purposes.

Better than I imagined!

Great trigger and easy install

Easy to install and improves the trigger remarkably so.
