i thought I wouldn't like them but bought one for one of my ar15s and actually came to like it. It kind of settles me down when sometimes I tend to rush a shot. I ended up buying 4 of them. Only thing I didn't like was I put one in a ar15 blackout pistol and find that when you want to shoot fast its kind of distracting because when your shooting fast you want the trigger to break fast and don't have time to "stage" it. But they make an excellent trigger for hunting or long range shooting.
Location: 3 miles NW of Brownells retail store and they keep me broke!
My Weatherby Vanguards all have two stage triggers and I love them. On a running coyote I can feel the slack take up and know that I am at the point where the trigger breaks. I take up that slack and hold it until the lead feels right and then roll that coyote up in a ball. I'll never use anything else.
I have no problem with two stage triggers for rifles but I've been pulling them for a long, long time. I find a nicely set-up two stage trigger much more desirable than heavier pull single stage. About a 2.75 lb. - 3.5 lb. pull works for me in either scenario.
For pistols a single stage around 2 lbs. is what I like.
Personally I hate two stage triggers and won't ever have another gun with one. To each his own but for me they aren't the way to go.
I didn't like them either for a long time. However I do a lot of shooting in the cold when it is <20 degrees. I don't know how many times I cussed under my breath while shooting at a coyote with a single stage trigger while wearing light gloves. It was hard to know just when the trigger was going to break. The two stage trigger fixes that for me.
When I was shooting USBR Competition I always shot a single stage trigger as shooting barehanded from the bench is a different scenario!
