I love me a flat trigger shoe. When I saw this “Stinger” trigger from Nelson Precision Manufacturing — a company rapidly gaining notoriety for its AR.5 bottle opener — on CZ-USA’s Instagram feed, I knew it was going on my Scorpion . . .
There’s the factory unit. It’s FRP — fiber reinforced plastic, or “polymer” in gun marketing parlance — and has a pleasing curve to it and a vertically-serrated face. Just like the magazine release I replaced, there’s nothing wrong with it. Of course, and again just like that magazine release, this doesn’t mean there’s no room for improvement.
We’re strictly talking about the trigger shoe here — only the part you actually put your finger on. Nothing about the mechanics of the fire control group is changed. Nelson’s Stinger trigger is a very simple swap, replacing the factory unit and reusing the same roll pin to hold it in place. It fit precisely on that little steel bar that protrudes from the bottom of the FCG.
The Nelson piece is machined from 6061 aluminum and is then hard coat anodized. A beveled edge around the roll pin hole made installation of the pin nice and smooth. Fit was spot-on snug. All edges also receive a slight bevel, including the left and right edges of the trigger shoe’s face.
On The Range
I’ve probably said this a zillion times in other articles and in article comments, but I like flat trigger shoes. Something about how it feels on my finger is pleasing to me, and I love the aesthetics of it in most cases — definitely including this one. The horizontal serrations on the front of the Stinger trigger worried me a bit based on photographs, but as it turns out they’re completely comfortable. Less surprisingly, they’re also grippy for confident purchase.
As usual, the feel of metal over polymer is a plus in my book. Basically, the Stinger hits on all of my preferences and it improves the on-the-range experience even if the trigger pull itself isn’t changed. Improve the feel in multiple ways, improve the looks, and you’ve improved the shooting experience.
