I recently picked up a Used G23 and the born on date is mid 02 the guys @ GLOCK told me. Anywho, I replaced the recoil spring with a new stock one, but what say you guys about replacing any other springs? Such as the firing pin spring? I have no problem with the way the orignal feels, and I try to keep the GLOCKS as stock as possible, with the exception of the ESSL, and Ext mag catch. I know you should replace the stock spring every 3000rds (that's what GLOCK said anyway, so I'm liable to listen to them, though I'm positive they last much longer than that). SO what I'm getting @ is this, what would you replace on a used GLOCK to make it run as close to as new as possible? Does the firing pin spring wear out like the recoil after a while? Or do I have nothing to worry about? I was also thinking about a new trigger spring also. Will GLOCK send me these parts if need be? Sorry to be long winded, this is my first "used" GLOCK. Thanks guys!
