Why would you just replace the recoil spring and not the entire trigger kit. Replacing the spring alone will give you a stronger trigger pull and for what reason would you want that? If you are having light strikes with the stock gun, then you have other issues. I installed the complete kit and after firing a couple of hundred rounds with no light strikes, I put the stock spring back in. Still have no light strikes with different ammo, a lighter pull and yes, I smoothed out and polished all areas in the bottom assembly as suggested by reading numerous posts from other BG owners.
A stronger recoil spring installed will cause the gun to be harder to rack and will help absorb recoil but poster was referring to the hammer spring. Just curious if any owners of stock BG 380's, without any mods, experienced light strikes.
I went with a heavier recoil spring in my LCP. Very satisfied with the reduced flip/snap. Yes it does make it a little more difficult to charge your firearm but the trade off is worth it in my opinion.
Note... Galloway is a middle man operation. They purchase their springs from Wolff, a long standing quality spring manufacturer, which is where I got my springs ... direct. I would rather deal with the manufacturer personally, and I usually receive much better service in return.
I don't care for Galloway's other products and gimmicks. Not impressed....
