Like the title says, I'm thinking about changing the recoil spring on my 4.5" XDM .45 ACP (possibly my 5" Kimber .45 but I am testing the stock springs tomorrow) so I can run some light handloads I've been working on with Clays and Titewad. The current weight of the recoil spring, after some research since Springfield doesn't post it, is 18lbs. Trying not to derail my own thread, I'm reluctant to increase the powder charge I'm using (3.3gr Titewad, 1.25 OAL = 767fps @19,400 psi) even though it's SO close to functioning I feel like I'd be better served swapping out the recoil spring. Since the factory spring is 18lbs, my decision is going to either a 16lb spring or a 14lb spring. I'd prefer to make the smallest possible swap to gain function, but I also don't want to buy a spring that doesn't fix the problem. And if I DO go to the 14lb recoil spring, would it be wise to run a reduced power striker spring as well? Recommendation on who/where to buy the spring(s)?
I have no experience running anything other than stock springs so hopefully y'all can shed some light on it for me. Thanks!
