"Major trigger-pull weight reduction"

Daniel Ward on 11/6/2012 5:38:31 PM

Overall Product Rating:


I bought this to install in addition to converting a P2000 Variant 2 LEM to a Variant 1 LEM in order to improve trigger pull. Before swapping the trigger return spring and the firing pin block spring for the lighter ones, I swapped this (the mainspring) and noticed a huge difference over the factory V2 trigger-pull already. I am not concerned about light strikes, as I had this mainspring/"hammer spring" in a P30 LEM and have never experienced a problem. I would recommend this for people look to ... More details

I used this spring to get to a V1 'light' LEM on my P30. Works great - and easy to install. Go for it.

"Great product"

I've been having light primer strikes so I replaced the firing pin, firing pin spring, firing pin block and firing pin spring but still had the problem. I then I bought this hammer spring and boom no problem at all with any ammo. Only problem was that it increased the trigger pull weight a little during full trigger pull yet is still bearable. Would definitely recommend buying also they have fast shipping.
