Gray Guns Flat Trigger for the PX4

Works and looks great on Px4 SD .45

I was skeptical at first, wasn't sure about the effect on the DA trigger pull. Figured I'd give it a try as every other widget Ernest Langdon has come up with, that I've installed one one of my PX4s has been a keeper. Installed it on a full size 40 S&W I'm using at a local range hosed competitions. Didn't want to test it on my CC PX. In my opinion the trigger angle didn't adversly effect the DA pull as I thought it might. The more I've used it, I've actually come to prefer it over the factory curved trigger in DA. Where the trigger amazed me was in SA. I was surprised by how much faster I could run the trigger. Have to bring the rest of my gun handling up to the new capabilities of the trigger. lol Definitely going to get another one to upgrade the CC PX.

My transition from da/sa during firing was aided greatly by installation of this trigger.

I bought two of these triggers one for a px4 I've owned since they came out and one just in case I come across a deal I can't pass on totally changes my px4 from good to great.

The stock trigger has a bit of give from the polymer molded over the metal structure. This all steel trigger, plus the fact that it is flat provides much better control over DA and SA shooting. Loving it so far. Now anxiously awaiting an improved trigger bar and my setup will be complete. Highly recommend!!

I have not yet installed the trigger. I never liked the stock curved trigger, and have wanted a flat trigger ever since I bought the pistol. I will write another review after I have installed and tested the new trigger. I asked Langdon about a flat trigger over a year before they announced this new offering. I was very pleased when it became available.

The Langdon trigger job and trigger job in a bag are absolutely amazing performance upgrades, but they don’t necessarily include replacement of the trigger itself. They replace the trigger group and trigger bar, but typically re-use the stock polymer trigger. I love straight, flat, performance triggers, so when I saw the Gray Guns trigger on the Langdon site, I knew I had to get it. When I originally saw the photo of the Gray Guns trigger, I thought the distance of travel was way too far, but it’s actually perfect. The photo shows it in the double-action position. I carry concealed, one in the chamber, hammer down (de-cocker). That extended travel in double action is an additional safety measure that helps to keep you out of trouble when you draw, holster, etc. In the single action position, trigger travel is obviously much shorter. I couldn’t find ANY instructions or videos on how to replace the PX4 trigger, but it was really easy to figure out, and obviously any competent gunsmith could install it also. Here’s how I did it: Unload the firearm/safety check/remove the slide Use a small punch to remove the pin holding the stock polymer trigger in place Remove the old trigger and trigger spring Insert the new trigger Partially insert the trigger retainer pin to line up the holes in the trigger and the frame Depress the trigger Re-insert the trigger spring above the new trigger with the tailpiece behind the trigger Push the spring down and hold it in place with a large punch so the holes line up Tap the partially inserted trigger pin in further to secure the spring and trigger to the frame Function Test... Done. I took my PX4 to the range the next day and I absolutely loved shooting with this trigger. I find that I shoot more accurately with a flat trigger since it’s easier to pull it straight back. I installed the Vantage Point Armory light-rail mounted compensator as well. Now my LTT PX4 Storm Compact Carry is perfect…

It was easy to install, after reviewing videos instructions on how to install a trigger on the Beretta PX4 Storm pistols.
