I have a SIG 1911, 5". I bought an 18.5# Wolff extra power recoil spring for Buffalo Bore +P loads and they shipped it with an extra power firing pin spring, which I installed. The extra power recoil spring works great with +P loads but doesn't always lock the slide back on the last round when shooting regular pressure loads. I would like to be able to switch recoil springs depending on which load I use (I think the stock spring is 16#).
Switching the recoil spring takes seconds, but the firing pin spring is a bit of a pain. So my question is...when switching back to the lighter (stock) recoil spring, is there any reason I can't just leave the extra power firing pin spring in? Will it cause any sort of potential problems? I've fired the gun with the lighter recoil spring/heavier firing pin spring combo and it works fine, but I haven't exactly put a 1000 rounds though it like this.
Any thoughts?
