I have two XD's, a 45 tactical and an xd45c. They both stay with a round chambered 99% of the time. How often should I change the striker spring, or should I just decopress the spring for a while? I cycle mags once a month because I used to have an issue with a 1911 that the mag springs would get weak after a year or so. I was wondering if this same concept could be applied to the striker spring? Your thoughts are appreciated.
