D Model Hammer Spring

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.

SOP for PX4 and 92 models. Improves trigger with 100% ignition reliability. Easy install.

My 92G ignites all 9mm ammo with a 12# spring, but I needed this when using a .22 rimfire conversion.

If you’re like me and saving for the trigger job in a bag but want a great fix quick for trigger weight reduction, buy the d spring. Makes a very noticeable difference and goes for a great price with fast shipping from Langdon tactical! Highly recommend this product.

Worked great in my 92A1. If the ends were polished it would be perfect!
