Umarex Gauntlet: Trigger Two stage(ish) Mod

In this installment of my Gauntlet series, I address the single stage trigger. The single stage trigger on the Gauntlet is completely adjustable and you can adjust it so that it breaks a very predictable point every time but I like a 2 stage trigger.

I like when I feel the trigger on my finger and I start to pull it back and it slides very easily and then firms up against the 2nd stage.

I know right there that a little more and it will break sending lead hurling towards my target. Because I do so much pesting and the bob and weave sometimes you must have a trigger that you completely know where it will break.

You can get the first stage down to just a few ounces with the lighter spring (and polished contact surfaces). The "wall" you feel for the second stage is determined by the spring plunger, and since it's located about a third of the way between the trigger blade's pivot point and your finger, you will feel about a third of its initial force.

So let's say you get the first stage down to a half pound (8oz) with a lighter spring, and you select a spring plunger rated for 3lbs extended (initial) force, you would feel an increase of about 1lb when you reach the second stage...or about 1.5lbs total just before the sear breaks and the gun fires.

All tools are listed in the video and there are only 2 specialty tools that most people may not have and they are as follows:
