This was covered a few times. I'm still in te process of " tweeking "
mine. The first and easiest is to remove the trigger guard from the
rifle ( two screws ) I was told to remove and rebend the spring in
this assembly, however, I found it much easier to simply take a
good pair of needlenose pliers and at the base of the spring ( you
will know when you see it ) take it and rebend at that point. You dont
even have to remove it. Dont overdo it since the trigger still has to return to its original spot after its pulled. Worst case scenerio is that you have to replace a 3 dollar spring.
Lube it and give it a try. While mine is noticeably better, I'm going for
about a 4 lb pull. That means I will have to take apart the hammer spring
assembly and mess with it. I'm not looking forward to that. I've asked
but still havent received a reply whether tat could affect the cycling of the
rifle. The trigger spring mod shouldnt interfere w/ cycling at all.
There is a somewhat detailed account on mods concerning this weapon.
Keep checking this site. Its in here somewhere.
