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? |

apparently just makes it harder for inertia to accidently fire. but the link above goes pretty indepth into it. sort of like springfield with the lighter firing pin and heavy spring. |

Thanks!
One thing I can't figure out from reading that...does the heavier firing pin spring need the heavier recoil spring? In other words, if I've fired hundreds of rounds through the 1911 since the heavier firing pin spring and heavier recoil spring have been installed, can I say that yes, the heavier firing pin spring works, and will continue to work with the lighter recoil spring back in the gun? |

Thanks all. What are these EGW/Wilson firing pin stops and how can they have so much of an effect on recoil? I've googled them and found that a lot of people like them but I can't find anything on how they work. Basically the slide stop is what contacts the hammer and cocks it as the slide moves rearward. Think of the hammer as a wrench, and the force of the mainspring as a nut. The longer the wrench, the easier to turn the nut. The contact point on a standard firing pin stop is radiused (rounded) moving that contact point on the hammer further away from the pivot point (hammer pin). The EGW and Wilson firing pin stops come with out the rounded edge, which moves the contact point on the hammer closer to the pivot. The extra effort needed to cock the hammer slows down the slide at the beginning of the rearward movement instead of towards the end like an extra power recoil spring. You just add a slight radius to the flat slide stop, just enough to break the sharp edge. This also means it will be harder for you to rack the slide. |
