    My sig jammed, can anyone help?

    Took the baby out today, P229Enhanced Elite .40.
    I went up a mountain, under some trees, there was lots of fog so we were practically getting rained on. I had 180gr Winchester cheapo whitebox stuff, and some Remington UMC mega pack 180gr. The Winchester jammed about 5-7 times through the 50 round box. Pretty sad. The Remington only had 1 or 2 out of 100 rounds. I am a noob, so please bear with my lack of knowledge and terms.

    I believe it was jamming during the feeding process. The spent casing was ejected properly every time, but upon loading the new round from the mag, the slide would not return all the way forward. The rounds were seated in the barrel fully it seemed, but the part that is pointed to and says "LOADED WHEN UP" was not being lifted by the round.
    I didnt take photos then, and I dont have any snapcaps, actually have some coming from amazon soon so I can mess with those when I get them, as I dont really want to be playing around with live rounds in my house.

    The groove in the barrel that is supposed to fit with that part was not fitting all the way in, even though the round was fully seated into the barrel.







    Excuse the mess, I am about to clean it. Wanted to post this before I get greasy.
    It worked most of the time, but the first maybe, 2000 rounds, I put through without issue. Then today I had maybe 10 failures. I want to know why.
    Does anyone have any ideas? Could it have been the wet and slightly warm weather? That idea doesnt sit well with me. The mags? My spring? The ammo?
    Maybe the round is being loaded into the barrel before the slide can return to the proper position and instead of pushing that part up and being seated properly it was pressing against it.


    Also, on a side note, is that little gouge, seen in the last photo on the back left of the slide, is that from improper greasing? I used it right out of the box when I got it at first. No more than 500 rounds, but I think it did that. After those first few trips, maybe even only one, I learned to grease it well.
    Thanks everyone, have a good night.

    Are they factory mags (MEC GAR)? Are you limp wristing (normally causes FTE, not FTF)? I think if you have fired 2000 rounds without issue and now you do I would give it a very good cleaning and lubrication. From the pics it looks pretty dirty with a lot of brass deposits. Did the LCI make a mark in the FTF case?? if It did it may have crap in it not allowing it to function. If you still have an issue after a thorough cleaning and lube, it will be time to look deeper.

      You win some and you lose some with some batches of ammo and it could very much be a quality issue, but a good through cleaning would be in order. Pay attention to the feed ramp, and very lightly coat the ramp with gun oil.

      That gouge, as long as it is not deep enough to deform the lip of the slide shouldn't cause a problem. Looks more aesthetic than anything.

        They are factory mags. Tried 2 different ones. Pretty sure I am not limp wrisitng. I am just finishing cleaning right now, gave it a good go tonight after taking it out in the wet conditions.
        What does LCI mean? Is that the orange part I am mentioning? There were slight marks in the cases, yes, but nothing major. I actually fired a few of them again with no problems. One or two of them jammed again and I threw them out. Next time I will remember to take a lot of pictures of everything going wrong.

        I appreciate your time and input, thank you.

          QC on factory Winchester stuff lately has been abysmally bad. I'd try other ammo and see if it clears up. 100 value packs right?

            LCI means loaded chamber indicator or that bar on top of the slide when a round is in the chamber. Something only found in CA, you should have single shot'd a regular enhanced and got one without that feature.

            Anyways clean that sucker real good and make sure it's properly lubed and if it still has problems then have it checked out if a different kind of ammo doesn't fix the problem.

            I'd try some federal or some speer I've never had a malfunction with federal ever when the gun was clean and lubed correctly.

              Thanks, Black Majick and dfens. It was Winchester value pack stuff. It was pretty clean, I haven't done more than a field strip, I think I would be in over my head. Do I have to do more than that to clean the LCI?

                LCI = Loaded Chamber Indicator.

                No limp wristing = good.

                Factory Mags and multiple mags eliminates a mag problem (unless it was only one of them).

                Based on your description of the FTF issue and the weapon not going into lockup I would really look for marks from the LCI in the cases that did not feed. This may be an indication that the LCI is not allowing lock up. Clean and inspect The LCI thoroughly.
                Another thought is to use a go no go gauge and check the ammo you were having problems with. If you don't have a go/no go gauge, pull out you barrel and use the chamber to check. The rounds should fall completely into a clean chamber. If they take any force to chamber and your chamber is indeed clean, you may have as stated above, a bad batch of ammunition.

                So far it sounds like your doing everything right.

                    Would a simple slide swap eliminate the lci all together or is some part of it in the frame

                      According to a local gun smith (Bolsa Gunsmithing), the rim on the winchester ammo you are shooting is not "clean and sharp" but has a bit of a bevel to it, not giving the extractor decent purchase on it. Also, it looks like you may be shooting your gun too "wet".

                      I know none of my Browning hi -powers will function reliably with the Winchester white box WalMart bulk ammo. The all function perfectly (zero failures) with UMC, PMC and Federal ammo. All my other weapons eat anything i feed them

                        Hey Ronin, thanks.
                        I put quite a bit of grease on the rails of the slide, to prevent grinding/gouging. It then rack the slide quite a few times and clean up excess grease the gets pushed out. I will try a little less next time, see if that helps.
                        That is what you meant by too wet, is too much grease?
                        Or the rain?

                            Not straight or what? I appreciate any help/input, I'm relatively new to firearms and not very mechanically inclined.
