While we are on a related topic, I just got back from the range and had my first three jams... Check it out...
New SigP229 9mm. Put through about 500 rounds without one jam.
Then, today, while shooting 200 rounds, had 3-4 jams. All of the jams were the same: the cartridge failed to eject from the chamber, and the next round was loaded either in the chamber pushing the spent cartridge upward, or somewhat behind the spent round and pushing the spent round into the barrel.
Thoughts? I am thinking that I may have over-oiled it. That seems to be the most logical considering the firearm is brand new and it did not happen during the first 500 rounds.
I think this is called stovepiping... So perhaps I shot a few limpwristed? Although it is weird how I have not had this happen before. Maybe a limp wrist combined with too much oil caused it...
1. Were you using the same type/lot of ammo?
2. Never apply excessive lube to your weapon! If you do, the lube will attract all sorts of dust-bunnies etc. that can cause your weapon to malfunction at the most "inappropriate" time! It can also penetrate your ammo primers and again, cause you great "embarassment" at the moment of truth!
I use a very light coat of "Marvel Mystery Oil". It has low viscocity,doesn't penetrate ammo primers and doesn't attract dirt.
3. "Limpwristing" can cause stovepipes. Adjust your firing position and hands ensuring that you have a firm grip, but not an excessive one.
Thanks ODA. Yes, I was using the same type of ammo, but not sure if it came from the same box - they were probably different boxes considering the frequency of the problem. I.e., the second cartridge of the day was the first to jam, and then it happened 3-4 times during the next 200 rounds.
I am thinking that it may have been excessive lube because A. the gun is new; B. the magazines are both new. Maybe the lube caused the cartridge to get stuck on the inside of the chamber? I am no expert, but that seems like a possibility.
Right now I am letting BreakFree soak in, and then I am going to do a clean and barely provide any lube - just small dots of Slip2000 on the slide rails and a little on the outside of the barrel. Should I have no lubrication on the part of the barrel where the cartridge sits inside the chamber?
