Years ago, I was trying to get my Bobcat to cycle better and also thought about the twin recoil springs that ride under the grips of the gun.
But first, I polished the feed ramp, chamber, recoil spring levers, slide rails, hammer to slide points, etc. Not much of an improvement, though.
Still, I thought I might have some success by cutting off a coil or two off of each recoil spring. It actually seemed to make the gun run worse as sometimes the slide wouldn't have enough oomph to finish chambering a cartridge. Because even if the hammer spring adds to the recoil springs' strength during recoil, the hammer spring does nothing to help close the slide back into battery.
So my brain says, why not use the full strength recoil springs and try a lighter hammer spring? That's when I tell my brain that its a rimfire gun, with a tiny little hammer trying to light off the cartridges. As usual, I typically have to leave my rimfire hammer springs alone no matter the gun.
The bottom line for me was that gun ran best with a clean chamber and with CCI MiniMag solid nose ammo, no matter what I tried to make it run better. Even then, I could only expect 4 to 7 magazines full before I had to clean the chamber and breech face again.
