Looks like too much luving.. not good
Having some issues with my 229 the last 2 trips I made to the range. After I shoot roughly 50 rounds it starts to have some failure to feed issues. I have been using Reliant Ammo 180gr FMJ and HP ammo. I need to test the gun out with some different ammo, but I was just posting to see if anyone else has had FTF problems with a 229. I took some pics of the problem when I got back from the range.
Jared,
You got a great gun there as I have 2 earlier non-railed 229 40's with a combined total of 13k between them without any problems.. hot days or "cold days"
Couple of things I'm seeing in the pics.. It looks like you've got the rails and guides packed with gun grease - way to much from what I'm seeing along with migration of it down on your trigger just under the frame. Too much luving - luving your gun to death, smothered in lube/love IMHO with "more should be better" when it is not - it will choke your gun as fast you found out especially if temps are cold and if you're running on old dirty grease or oil combo. Your gun is dirty/contaminated along with mags most likely at this point.
Too much grease like too much oil will not stay put while the repeated forces of the cycling action occur, any over-flow will fly back and down mixing with hot spent gun powder, quickly, and this goo goes 3 places quickly.. And if left uncleaned will mix and hot-stick, once it all cools down like fly crap (and build up) - not good
1. Back and down onto each chambering bullet - thus your barrel chamber is contaminated enough to aid in what are the causes of your gun jamming as is the feed ramp becoming contaminated.
2. It goes back and "down" and with each last shot it gets your mag follower very dirty quickly along with getting inside your mags spring and interior walls from top down to about the 1/3rd the way down.. quickly
3. Also, too much grease in "cold temps" gets thick, remains thick and actually slows down all cycling timing in regards to slide.. timing off, jams occur
Not knowing what the temp was that day and what it is I'd suggest a few things..
Clean your gun - if cold, try gun oil and using a Q-tip with a couple of drops of oil on it from the center of each rail and guide, one swipe back and forward resisting the_urge that "more must be better".. it is not - as I said what isn't sticking as oil "film" does when very thin, flies back and down and simply migrates, via gravity, down until that area of too much, to start, has a film left behind which is what will work for any range session of 500 rounds or more in a day.
If you want to stick, lol, to gun grease, again, using a Q-tip with a little grease swirled on the end, center of rails, one swipe back and forward, wiping any excess off or thinning it with the other dry end of Q-tip..
Ice like, seen, sheen is all ya need.. and will keep your gun a lot cleaner, longer because none of it is flying or migrating as can be seen in your pics under the slide on the frame.. too much - "less IS more"
Mags, depending on how many rounds you've run thru them, but mags are easy to inspect, clean as you need that follower to slide up and down freely with no hang-ups that will change the angle of bullet delivery and cause feed jams
Clean gun, using right lube for Temps, be it oil or grease, thin, ice like sheen, only, with excess simply wiped thin will do the job with your Sig 229
Oil, IMO, for guide rod and spring and after blowing up your pic, I'd suggest chking extractor claw for build-up/contamination, as well, as this is another area where blow-back hits and sticks and builds up especially with grease and or combo grease and oil.. with too much here, there, wherever you use lube. "Less IS more" - believe
OMMV on less is more, but -
Let us know how the next round goes
Ls
Ps.. new gun or used and if used, how many rounds "aprox" do you think it has on it - if used and unknown round count, I'd replace return spring as well asap
