Took my newly overhauled Sig 226 out today for the first time since I got it back.  Had some interesting problems.  Several times a round would be completely nosedived  into the magazine.  It would eject the prior round, but then I would find that.  It also won't hold the bolt open after the last round.  It will if I insert an empty magazine and rack the slide though.  These are all mags I have been using for two years and have never had this problem.

Am I just dealing with a breaking in period for the new springs?  

Any thoughts?

You sure the mag springs are in the correct way????

You are shooting full loads?

The bottom of the breach to bottom of slide on the block doesn't have a edge bur?

Mags haven't changed since I bought them a couple of years ago.  Worked fine until the gun went back to Sig.

Shooting WWB bulk pack and some reloads.  Same problem with both.

I'll check on the burr.  Shouldn't be one there.  This is an 18 year old gun.

Sounds likely the new springs are behind your problems, but I don’t know if they need a break in period or if they are an indication that your mag springs need replacement (assuming the mag springs weren’t also replaced).

I’ve always considered the mag springs on the older German made mags to be pretty weak anyway, plus they don’t seem to hold up too well (and now I’m assuming you’ve got the older mags and not the newer MecGar made mags with the much stronger springs!).

Also, when my former agency went to SIGs many years ago, I occasionally saw a shooter have a SIG mag where for some reason the rounds suddenly appeared to just get jumbled up in the mag.  This sounds similar to the nose-dives you’re having.

It didn’t happen often and I never got a good handle on what caused it, but I always suspected weak mag springs.

Thus my guess is you should first either replace your mag springs or get a new MecGar mag and see if that solves anything.

Alternatively, try some hotter ammo (say +P) and see what happens.

The mags are all used preban factory Sig with the zig zag down the back.  

I'll try replacing the springs and see what happens.  

I thought it odd that it would lock the slide back on an empty mag if I just racked the slide, but not when I emptied a mag.

Quoted:

Actually, that’s fairly common for some folks.  However, it’s generally a result of things like inadequate lubrication, thumb on the mag catch, limp-wristing, weak ammo, and such.  None of these seem likely in your case.

Typically SIGs don’t require a break-in, but I’m wondering if you’ve got a point about the replaced springs needing a break-in (to take a little bit of a set).  It might be that the new recoil spring is a bit strong at the moment.  If you’ve got the old one (which I doubt), swapping it out and seeing what happens might be interesting.

Anyway, you’ve got the older German-made mags I was talking about, and IMHO it’d be a good idea to replace the mag springs regardless – at least for any mags that you’ll be using for self-defense.  Note that they take a totally different spring than the newer MecGar made mags.  Be sure and get the right ones.

Getting a new MecGar mag (which I believe has a higher capacity than the old mags) and trying it out might also be worth considering.

I just ordered several new +10% Wolff springs for the mags.

This was my everyday carry gun.  Can't do that right now.  I'm relying on my CZ-52 for home defense right now.

They did send back the old springs.  I'll have to give that a shot this weekend if the new mag springs don't make it.

Installed new springs in my mags today.  The old ones were so bad they barely expanded when I removed the floor plate.  Considerable difference loading rounds with the new springs vs. the old.  Hoping to get to the range this weekend to see if that was the problem.
