I recently installed the kit with the optimized trigger bar,and 11# trigger spring. To say the least the reset is crisp and the DA/SA is much lighter cant tell the number. I carry mine off duty and love the PX-4 unfortunately has never gained popularity guess folks like them striker fired pistols. Iam like Ernest cant beat a DA/SA pistol cant get safer.. In closing the factory trigger is good but trigger job in bag is better. Well worth the $214. I to have put many rounds down range with it and this is a vast improvement. The LTT folks are great and will answer all your questions. Stay safe and keep practicing. Regards M Gander Paris, TN

i was pleased with the trigger pull out of the box. but upgrading the trigger job drastically improved my single action. it's magic.

I have these in all my 92’s and knew this would be a must for my new PX4. Everything comes assembled and lubed, so you can drop this in and be shooting in minutes. There is a shortcut to not having to remove the back strap, so make sure to find the right video!

I LOVE the Beretta PX4. It is my everyday carry and even in its stock configuration it is an outstanding firearm. However, this trigger makes this thing feel like my competition gun. The installation is easy with the video tutorial and the results are absolutely fantastic. I can not recommend this product or any Langdon Tactical product enough. Great company, great people, great products. 10/10.

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
