I just purchased a 1977 Browning BDA 45. I believe the stock recoil spring was 15 pounds. Would it cause problems to go to an 18 pound spring? I would like to batter the frame less.

I don't see any harm in trying the heavier recoil spring. If it slows the slide too much, the worst that will happen is poor ejection of spent cases and/or feeding new rounds from the magazine.
I don't think you really need to worry about your new BDA, however.
Welcome to SIGforum, by the way.
If everything works as it should with the heavier spring, No worries.
When swapping springs, it is best to start with the heaviest spring and work down until you have one that cycles properly with your desired ammunition.

Welcome to SIGforum.
I do not believe an 18# spring will be a problem.
Niech Zyje P-220
Thanks all. It's my first Sig. Found it at a gunshop incorrectly marked. Got a decent deal and love it
That pistol is just an early P220 45, maybe polished better than the later Sig marked ones. I use the newer green marked spring in all of mine. The cases fall in a smaller pile, and the accuracy is even better.
Be careful with the triple strand green springs in the early model p220's. The early ones were milled for the single strand 15lb spring diameter and the triple strand green springs can bind very badly as the diameter of it is a bit large for the size of the spring seat in the slide. It may fit in seemingly fine, but when compressed from retracting the slide, the triple strand spring diameter gets even bigger and can bind badly (there is more room in the spring channel on newer P220's). If this is the case, you can get high quality wolff single strand springs for the P220 in various weights
Xer0 I was planning on getting them from Wolff, I'm assuming theirs are all single strand from what you are saying?
Yes Wolff's are single strand, unless somethings changed. They also used to sell 3 spring kits so you could try different weights for different ammo.
About 10 years ago I bought a 1984 manufactured SIG P220 in outstanding condition, for which some people here at the forum (more knowledgeable than myself) suggested installing a heavier spring and solid guide rod which I bought from Bruce Gray. The problem was that the new guide rod was stouter than the factory original and as a result could not fit into the slide. I mentioned this to Bruce and he offered----at no charge(!)----to modify the slide so that the new rod and spring would function properly. This P220 shoots great and many thanks again to Bruce Gray!
While I'm here. I have 5 mags that lock the slide back when empty. The other 5 do not.
The 5 that do not, look identical to the others but they have a rubber bumper on the bottom and a different follower. But the body is identical.
Is there a way to fix that?
I would replace the followers on the five (5) magazines which do not lock back with OEM old school SIG followers. Try this link to Gun Parts Corp. https://www.gunpartscorp.com/products/872430A
Thanks for the link! I was looking for them on there and couldn't find them.
