I had posted this in an older thread on the topic, but it may be that no one wants to answer an old thread. Not sure, but I decided to make my own thread on the issue.
I have two 40P's, one that has been cajunized and one that is completely stock. Both have the "lazy action" problem mentioned in other threads in this forum (slow to go into battery, or getting stuck part way into battery). I see the most common fix for this is to get a 20lb Wolff recoil spring. I've heard that the 40P can use a 75B spring that has been cut down, or a 75 Compact spring. My question is, does the 75 Compact spring need to be cut down, or does it fit correctly? The barrel is a different length between the two guns, at least according to my research. I'd much rather order the Compact spring to use if it doesn't need to be cut and avoid cutting the spring, if possible. If it works for one of the guns, I'm guessing it should address the issue for the other gun as well (at least I hope so).
