    This trigger kit made a significant improvement in the smoothness of the trigger action. Resulting in a more accurate firearm. Would strongly recommend for anyone looking for that extra bit of performance from their Ruger Mark IV

    I installed this kit with no difficulties whatsoever. The instructions were straightforward to follow. After the installation, the trigger system worked flawlessly. The trigger pull is smooth and crisp. Excellent for my target or completion use.

    I would give it 5 stars if it wasn’t lost in the mail. Don’t know when I will receive this item.

    Works as expected. The length of the over travel screw is just barely long enough. Should be .030 inches longer.

    good news, i installed the trigger. bad news, the old trigger spring flew into outter space while taking it apart. better news, the ultimate trigger didnt require it! easy to tune and feels really good. now i want a bolt.

    Good kit

    Posted by Steve-O on 4th Dec 2024

    This kit results in a nice trigger pull. The instructions are a bit lacking. I tried to remember how the parts I was pulling out were oriented in the pistol but inevitably there were two parts that required some type of "pretzel" installation and the written and video instructions didn't show how they were oriented during install. I have built 1911's and 2011's but it took me two hours to install this kit. You need 4 hands and 8mph wind at just the right time to invert the sear spring over the ledge in the sear while inserting the sear pin through the sear. If you have never installed one of these kits in a 22/45 buckle in and order a rubber stress ball or just grab a wooden stick to bite down on.

    I bought a new Mark IV and the trigger was rough to say the least. It had a lot of creep and a heavy pull. This trigger took out all of that and really makes a precision difference .

    Well worth the time and money. The installation video was very thorough and easy to understand. I just got back from the range and it works flawlessly.
