Sig spring

I think I need a new spring in my sig P229. I've been having a problem where the slide stops short of closing sometimes. I was thinking the problem could be one of three things, but maybe even all three... It only seems to happen when I practice and fire more than 30rds or so. I typically use winchester white box 100rd boxes. I was thinking the ammo may be dirty, or sig just makes their guns with really tight tolerances and a little dirty is too dirty, or that the spring just doesn't have enough spring to work the gun dirty. I wouldn't think it'd get too dirty to work right after 30 or so rounds. thinkin maybe just a slightly heavier spring may be the ticket?

How many rounds have you put through it since the last time you changed the spring? It's a good possibility that the recoil spring is weak. When I started becoming a serious pistol shooter, I noticed that my 1911s seem to cycle differently. Then I started having problems with the slide not locking up on some of my reloads. Then I started to realize that putting 8000rds though a gun meant I was about 3000rds past the time when I should have started replacing springs. After I replaced the recoil spring I started having other problems. Now the gun started stove piping. Then I realized my older mags needed to have their springs replaced because the timing between the magazine springs and the cycling of the slide was off.

If you don't know how many rounds have been put through your gun or your mags, you may want to just replace everything and keep better track.

Re: Sig spring

I got it used, so I don't know how many rounds went thru it in total. I have maybe 1000 or so thru it myself. It may be time for a new spring. That's what I was thinking anyway. I'm trying to get all my guns up and running in the best shape anymore. Seems like I've been doing that and hording ammo more than buying anything new for the last couple years now.

Re: Sig spring

Dex, while the recoil spring could be the cause of failure to go into battery it could also be caused by ammo, gun lubrication and cleanliness or shooter error in the form of a limp wrist.

SIG specifically recommends replacement at 5000 rounds. That is probably overly cautious but given the small cost of a spring not unreasonable.

I'd say ammo may be part of the problem. When I do carry, the sig is what I carry, so I always make sure its clean and properly oiled. Limp wrist isn't the case. I'm thinkin it wouldn't be a bad idea to replace the spring anyway just because I did get it used, so its hard to tell how many rounds the other guy put through it.

What do they call that spring? I don't want to order the wrong one.
