Works perfectly and Langdon Tactics has great customer service shipped right away
Not sure how much better it is, about 3 loops shorter than the original. Glad I got it, though.
The installation of the D Model Hammer Spring on my PX4 Storm full size has made a difference in the double action trigger pull. I now have the D Model Hammer Spring on my Px4 Compact, as well as my Px4 Subcompact. Couldn't be more happier.
Works as advertised. One of the best upgrades to can do for your 92 series pistol. I put this off for years- wish I would have done it right away. Much smoother DA pull with zero negatives. Also great service, great website, prompt order confirmation and quick shipping from Langdon. Thank you for being what business should be. You earned a lifelong customer. -Paul
Extremely easy to install. Big improvement over the factory spring.
Having recently installed the "PX4 Carry Lever (Decocking Lever)" on both my PX4 Compact and Subcompact. The "D Model Hammer Spring" was a welcome addition to both my guns. The improved DA/SA trigger pull was just what the doctor ordered. At the range, I had a great time re-familiarizing with my PX4's.
