Help!
I purchased a 2nd-hand Kahr K9 Saturday. All indications were that it was unfired. I disassembled if for a basic check and lube, then reassembled it and headed to the range. I did note during reassembly that the slide seemed to be heavily sprung, but I figured that a small, lightweight 9mm would probably have a stouter spring than a 9mm 1991, so let it pass.
At the range, the gun worked flawlessly through a box of 147gr Winchester 9mm ammo.
After I arrived home I again disassembled the gun for cleaning and noted that the recoil spring was deformed, with a "swelled" coil near the middle as if the spring was forced to run over itself during compression (over-compression). I also noted that the recoil spring guide showed significant battering at the back end, and the guide rod itself showed substantial wear as if the spring was binding heavily along the guide. See pictures below:

I went back to the gun store where the gun was purchased to inspect another Kahr K9, and noted that the spring in their K9 had 20 coils while the spring in my K9 had 22.5 coils. It seems to me that the spring is simply too large and was completely compressed during cycling, causing spring damage as well as damage to the recoil guide (the frame looks fine, though).
Can someone tell me how many coils there are supposed to be in the recoil spring of a K9?
Thanks,
