Need Sig Advice

[09rubicon]

I need some advice from Sig owners.

I was shooting my P239 at the range today and about round 300 I started having failures to feed. I figured maybe it was the ammo (I had several brands with me) so I switched, still a failure to feed about every 5th round. I then switched to a few other magazines including a new never used one. Still failure to feed. At this point I believe its about time to replace the guide rod spring. Then I had an issue.

As I was firing my last magazine I had another failure to feed (still trying to determine if magazine related at this point). I do as most of us do, finger off trigger, rotate gun to see breach and begin to pull it back towards me (from arms locked position) to see the obstruction. As I am pulling it back towards me, the slide slams home and the round discharges (no finger on trigger)! I immediately cleared and safed the gun.

So I am left with two questions. First is have any Sig owners had abnormal trigger or sear wear at around the 9000-10000 round mark? I plan to replace the guide rod spring and trigger springs then have the gun checked out by a competent gunsmith before shooting it again, but your advice and experience may help me narrow down the issues. Second, was this considered an ND? I am leaning towards a malfunction, but if the consensus says ND then I will own it. The round did go off when I did not intend it too. Thankfully I was practicing good gun handling and the round did go safely down range (even struck the target).

What say you Calguns, many of you have much more experience than I?

Not much help here, but I never had those issues with mine. I've since sold it, the P239 was the only gun I've owned that I never truly enjoyed. Mine had about 800 rounds through when I sold it. Hope you get it resolved.

Dont mess around here...do the right thing and send it back to Sig for them to figure it out !!!!

That's definitely an option. And may end up being the best. Though thru experience I have found a competent gunsmith can be better sometimes. All options open right now.

I've fired closed to 4,000 rounds of 40 and about 2,000 357 sig from mine and nothing has ever happene like that. I would go back to the range and try to recreate the problem? By the way, have you or anyone else done any trigger work on this gun?

Completely stock. No modifications at all, factory magazines.

You should have replaced your recoil spring every 3k and all the springs every 8k-10k rounds. Mag springs get replaced when FTF issues pop up and all other springs are known good.

If you are between 9k-10k rounds you pretty much want to change every spring in there.

The other issue could be a hangfire. How long did you wait before trying to pull the slide back?

In this case I am confident it was a worn guide rod spring causing the FTF. My greatest concern was the round discharging. Could have been a hang fire, but the round was only half in the chamber maybe 3-4 seconds until the slide went forward on its own and immediately discharged.

I have a full set of replacement springs ordered. Thanks for the insight.

Don't own any Sigs currently but I've had a few over the years (though admittedly never a 239). Never experienced anything like what you describe though I don't think I got past the 5k round mark on either of my pistols before I sold them off to fund something else. I any event, I was always impressed but how smoothly they feed rounds out of the magazine. As such, I'm a little skeptical about the feed failures being the result of a week recoil spring but I suppose it's possible. The more alarming issue is the slam fire -- that should really never happen and does seem to suggest to me some sort of excessive or unusual wear in the sear / trigger mechanism. Might be time to send it back to the factory for a look.

Im interested to see what you find or if you send it to sig. My p239 is a 9mm and I only have 200 rounds through it with no issues.
