This simple upgrade dropped the trigger pull from 4lbs 3oz to 2lbs 8oz. I love your installation videos as well. Great job brothers!

The MCarbo trigger spring for my Model 25 greatly improved its trigger pull. I have no way of measuring the trigger pull, but I am pleased with the change, which is noticeable.
The only problem I had is that the video does not depict the trigger assembly of my 1990's Model 25 Marlin. It was much harder with mine than shown.

Good Product and Good Value

Cons:
Installation took about 20 minutes because I had to let a screw soak up WD40 for a few minutes to loosen it. My guess is that the trigger pull is about half as much now. It's enough to be safe for hunting, and it's decent for target shooting. In any event, it's way better than the original spring on my 25n.

Great Improvement.

This product worked very well, lowering my trigger pull tremendously. I would highly recommend this to an owner of a Marlin 900 series trigger.

Great Investment

I bought two. I’ve only installed one in my 925. But, it probably cut the trigger pull in half. I’ve got a worn out and abused gun that I bought from a pawn shop to be my truck/trunk gun. It just happened to be the best shooting .22 I own. So, I figured I’d love on it a little. I now have a beat up squirrel gun that outshoots my nice 10/22. The trigger is literally perfect now. About 2.5lbs. No complaints at all.
