Sig 226 Problems

Is there any reason you're using the grease? Try just using Hoppe's oil, and your problems will almost certainly disappear.

The armorers manual suggested quailty grease over oil unless evniromental conditions prevented the use of grease. Sig even recommends a light brushing of grease down the bore.

I just end up with a little more grease than is needed, but the pistol "mostly" functions with superior lubrication and protection against the elements. There is a night and day difference in smoothness with oil vs grease... Grease wins out in my book.

I use grease on all my firearms with no issue other than the slide not locking back. I could thin out the grease on the slide a bit more, but not worth it for my needs.
 
I see that I'm not the only one with this problem. The ammo I'm using now is the same I started using when I bought the pistol, 124 lead RN. When I rackthe slide on an empty mag it works as it should, it's just when I fire the last shot it's having problems. As stated, it may be that I am putting a bit of preside on the slide release and not slowing it to go up all the way. I will check out my grip when I get back home later this week. I could also try some 147 TMJ that I have lying around.
 
I'm not sold on the "weak ammo" idea. I also used to think that years ago, and I even posted some comments to that effect on this board... :redface: It has a certain appeal to it. But I learned over the years that this issue actually has nothing to do with that. Baring a major mechanical issue (improper reassembly, severely worn out springs, etc.) or extremely dirty (or damaged, or improperly assembled) magazines, it is all about what your hands are doing.

Some of the very same SIGs that I believed required "hot" or "heavy" or this or that ammo to lock back reliably - they now lock back on the last shot 100% of the time with Remington/Winchester/American Eagle FMJ 115gr. (the mildest factory stuff you can get) - that is, if I don't hold the slide stop lever down with my thumb.

If you were loading 80gr. bullets with half the powder of a normal load or something like that, then maybe we are talking. But if the round is strong enough to reliably cycle the action, it is strong enough to cause the slide to lock back.
 
I recently had this issue as well. I'm a new sig 226 owner, its my first pistol. Im very new to pistols so i'm still learning. First few times I went to the range, i would baby the pistol, meaning after the range I cleaned it for like an hour until it was sparkling new again. I use militech 1 oil

I was having the same issue as well, slide wouldn't lock back. At first I thought it was my grip, my thumb was riding the slide catch, so I correct that, moved my thumb out of the way, but it would still not lock back. This happened after 2-3 trips to the range. Last trip I didn't clean it, left it dirty, and it locked back fine every time. I use 115grain ammo. So not sure if I am over lubing, I don't think so, I wipe the lub on with a cleaning patch, and make sure it isn't excessive enough that it runs under the force of gravity. So I dunno... I'm gonna clean it up good before my next range trip, lub it up like I have been doing and see what happens. If the slide doesn't lock back, im going to wipe off some lub and see if that fixes it. I function check it every clean and the slide always locks back with an empty mag in.
 
I have ran into afew out of spec slide catchs on my inspections. You can test it by removing the slide and push up on the slide catch "it should move freely" If not you have a defective part. But 99% of the time its the user rest his thumb on it ;)
 
I put my hogue grips on this weekend at the range. Well they push my thumb further away from the slide release and every magazine locked back as it should.

Some testing with snap caps showed me that it takes very little pressure to prevent the slide lock from doing it's job.
 
You might also want to check Sigforum as there is a stickied discussion there about the slide failing to lock back. There's more info there than you can imagine.[/QUOTE]

IMHO, this is the best advise I've read from this post. I won't even comment of some of the suggestions:rolleyes:

I say go to Sigforum. These are the Sig experts and will give you an expert opinion.

For the love of everything SIG, do NOT start cutting springs!
 
Cutting the recoil spring on any gun is generally a bad idea, mainspring you can sometimes get away with it, but recoil springs, usually not.

If you want to weaken a spring, shortening it is not the best approach, put the spring on a drill bit, start up the drill and get some emery paper and thin the spring wire slightly.

But frankly spring problems are best solved by Wolff springs.
 
bringing this back from the dead - but my 226 had the same problem brand new - after a few hundred shots, a good cleaning, lube, it started working beautifully - I haven't had an issue since
