hello again, i have another question, how long should i expect a magazine spring to last under concealed carry conditions? (.45 acp 24/7 pro) i am loading 10 in a 12 shot clip. the spring is already a little softer than when it was brand new, which is normal for springs, they usually take a set after a while. i am wondering if i should keep a couple on hand and replace them at some interval. i am also considering using "kal-gard's gear kote" (baked on HARD moly coating) on the inside of the clip so it will feed better. has any one tried that?
