Swap the hammer spring for a lighter one.
Thanks!Off the top of my head, the factory spring is a 21 lb. spring.
I wouldn't go lower than a 17 lb. and even at 17 lbs. there have been reports of the potential for light primer strikes.
Personally, I've had good luck with an 18 lb. spring.
Even dropping down to a 19 lb. spring from the stock spring should make a noticeable difference in your trigger pull.
Thanks! Ordered it last night.The Mainspring that you need to change, is annotated by the white arrow...
The seat, is located where the blue arrow indicates, and can be removed by pushing at the notch the blue arrow is pointing at to move the locating lugs of the seat up from their cradle. Substitute the lighter tension spring, and reinstall the nylon seat, from where it was located originally.
Wolff has a 19# mainspring for pistols with a plastic mainspring seat, your M11A1 should have, it's stock # 32419.
