This spring has lightened my trigger pull. I recommend getting the plunger spring and reduced striker spring. Using all of these make a big difference.

If u want to improve your hand gun using this is the spring u need

I am a casual shooter, and like to spend time at the range with a number of guns. Spoiled by several nice 1911s with ~3.5lb triggers. In the past year I bought a Walther Q5 and liked it so much that I then bought the steel frame version. That's where this spring went, and the feel is more like what I am used to. I can really tell the difference - it was ok before at 5.5lb, but for my uses this is better. Easy to install - I used a dental tool to hook and unhook the Walther springs.

Nicely made spring. Fit my SFX as it should. Only gave it 4 stars because my trigger pull with it went up to 3lbs 5 oz. from the 2 lbs. 12 oz. I have with a spring I cut and bent to fit. Was hoping for about 3 even, maybe with use it will go down.
