I have a pro carry II and needed a new recoil spring. I called wilson combat and they told me that I needed model 10sc20 #20 so I ordered 2 of them and recieved them today. I went to put it on and saw that it was longer than the stock kimber recoil spring (by about an inch) that was on the gun from the factory. Did I order the right spring, is it supposed to be longer? This is the spring that they told me was right for my gun. Any help would be greatly appreciated.
