I had bought a new 24'' bull in .44mag that was grilla hard to open!! I did alittle investigating and found the depth of the locking lug hole
was not correct !! I had ordered some new OE springs ! The spring that came with was bent and just to long! I did the math with the coils
and trimmed app 2 1/2 coils off the new spring and WoW!!!! what a perfect fix!! It is now a smooth opening contender!!!
