One of the questions I’ve heard most from Scorpion owners is “which replacement trigger is the best?” This is a hard question to answer, because a lot of people don’t understand how the Scorpion trigger functions and what they are actually getting with aftermarket parts. Hopefully, I can clear up a few things with this post.
First, what most people think of as the trigger is only part of a unit. This is important because while replacing the trigger definitely changes the feel of the trigger unit, there are a lot of other moving pieces that affect the trigger pull, such as the trigger housing.
The trigger housing actually has more to do with the feel of the trigger pull than the trigger itself. As you can see below, the hooks of the housing are what hold the hammer until the trigger is activated.
Fully aftermarket triggers, like the CZ Custom trigger, actually modify those hooks to shorten up the trigger pull. As you can see below, the hooks on the CZ Custom trigger are significantly shorter than the stock housing hooks.
Merely changing out the trigger will certainly change how the trigger feels against your finger, and possibly even the perceived weight, but it won’t change the actual length of travel or any grit in the trigger pull.
Second, another major factor in the trigger pull is the trigger spring, which you can see in the picture below. To truly get a better trigger pull, both the trigger spring and the hooks on the trigger housing, as well as the hammer, need to be looked at and possibly worked on.
For an individual looking to go all out, the CZ Custom trigger runs $221.46 and will do wonders for your trigger pull. Not only do the shortened hammer hooks shorten the trigger pull, but the pre-travel and over-travel adjustments also massively improve the break and reset.
ShootingSight.com also sells two trigger units (one is a compete drop-in) that are designed to significantly lower the trigger pull weight. I don’t have any personal experience with these triggers, but there are no mentions in their literature about the ability to adjust pre or over-travel. Their triggers run $199 for the self-install or $239 for the drop-in.
If you can’t afford that kind of money, one of the best parts you can purchase is the HB Industries Reduced Weight Trigger Spring Kit. In my experience, installing this kit reduced pull weight by four pounds. Another option to consider is the Shooter’s Element Internal Polish Job. For $45, SE will polish the hammer and hammer hooks to remove the grit associated with the stock trigger.
If you want to replace the trigger as well, you’ll have a lot of options, including HB Industries, Shooter’s Element, Nelson Precision, and Tandemkross. Of these options, only Tandemkross allows you to adjust pre-travel. I’ve tried each of these triggers with the exception of Tandemkross, and all of them offer improved ergonomics over the stock trigger. I personally prefer flat triggers, so I lean toward those options, but I still haven’t settled on my favorite yet.
