What pound recoil spring do you run in your gun?

[Pappabear]

I shot my CRG the other day and the recoil felt more aggressive vs my other guns. When I rack the slide, it does feel a bit easier to rack, but not significant. I doubt I have much over 3,000 rounds but I don't keep round counts. I know I should but I don't.

What Lb do you run and and what are the ranges of weights ? Its been a while since I replaced one, last one was in my TRP, and thats been a while.

18.5 pounds is standard for full-size guns

This thread makes my want to buy a "test" 1911 and shoot a few cases through it just to try a few of these combos...

All you would find is that the heavier the recoil spring, the harder they kick and the more they dip, the lighter the mainspring, the more they want to inertia feed.

Springs don't affect timing, they only affect slide velocity. In a 5" 45, I think the 23lb main and a 14-16lb recoil is ideal and haven't gotten a legitimate reason for the light main/heavy recoil spring setup. The boutique 1911 builders do it just to make it sound like they improved something, and it feels nice when you're checking out the slide to frame fit. It makes the slide feel tighter, but it's easy to cock and rack and makes fit 'n finish crowd get all emotional.

I have found that most extractor problems stem from goofy spring rates that let the magazine inertia feed.

I do 17# recoil/19 #mainspring, or 18#recoil/23#mainspring and change the recoil spring every couple thousand.

Standard 5" 1911 is 16# recoil spring with 23# main spring. The main spring does more to slow the rearward travel of the slide than the recoil spring, which the primary purpose is return to battery. A small radius or flat bottom firing pin stop, will work better to slow the slide than a heavier spring.

By increasing recoil spring rate (poundage) you will make the slide dip more on follow up shots.

I'm using a WC 17# flat wire in a full size 45 1911...It does require a different guide rod to go with the spring account the smaller diameter of the flat wire spring
2kish rounds, no failures...benefit of the flat wire spring is mostly longevity
