Is there any problems associated with using a reduced recoil spring in an Interarms PPKs? I find the slide a bit difficult to pull back, partially because of its small size, and from the strong spring. I dont have this problem with any of my other handguns. The factory spring is 20 lbs, and Ive seen 14,15 & 17 lb springs for sale. They also sell a 24lb spring. Any suggestions?
