Ok ive had my glock 23 for almost 3 years now, i started having feeding issues i marked the mags and thought i found the problem because they are the CA 10 round mags but i bought another and have a 15 round mag, today i went out and every single mag jammed 2-3 times. I was using the cheap federal from walmart so i need to try different ammo but ive put almost 1000 through it with only an occational failure to feed with one of the mags. Any suggestions or ideas of whats wrong.

How many rounds do you have through the gun, total?  If you don't think that it is magazine related, then you may try replacing the recoil spring.

If Wolff makes springs for these I'd go with them.
May as well order new extractor spring at same time.  Wolf spring kits are cheap for what they will do in some guns.
Total different beast but it made my 200 dollar Cabellas Uberti a different gun completely.
Also was cure for .45 automatic I had years ago.

1000 rounds shouldn't warrant the replacement of anything really, was it bought brand new or used?

Before you start replacing anything, get some different ammo to test with.  Could be just a bad box of rounds.

It was brand new when i got it, i had 10 left in the box i shot and there is black like grease or something on the rounds the other boxes i have look clean, but ill buy another brand and try it out. I think i might buy a lone wolf recoil spring anyway just in case and its probably good to have.

Things to try:
1. Different ammo. Federal Champion is weak stuff. Winchester White Box should work better. I've never had a single problem with American Eagle or Speer Lawman in my .40 Glocks.
2. A new guide rod assembly, factory weight spring of 18lbs.
3. Disassemble and clean the magazines.
4. Detail strip and clean the slide and its internal parts. The extractor may have residue built up around it, causing it not to move freely enough. I'd use something like rubbing alcohol. If you use oil for corrosion protection, wipe every part and internal area of the slide absolutely dry afterward. Using oil in the slide internals for corrosion protection will collect more residue and require more frequent detail strip cleaning.
5. If it happens with some magazines and not others, replace the magazine springs. Limited capacity 10-round magazines use different springs than the standard capacity magazines.

On the following page are some Glock Armorer's Manuals, just scroll down to the "G" section. I learned from the Update Manual and 2009 Manual. The 2009 Manual has a few pages missing, but that info can be found in the Update Manual as well. (the author of that site specifically requested not to hotlink to his page)

Here's an easy way to disassemble and reassemble the firing pin assembly:

NOTE: Older followers attach to the spring by putting the end of the magazine spring coil through a plastic loop on the bottom of the follower(like the follower you see in the above video). The newest followers don't have that loop, they simply have two plastic ledges to hold the spring in place, so pull the spring out of the follower until it "pops" out of the follower and push the spring into the bottom of the follower until the spring "pops" into place in the bottom of the follower.

I know the .40 S&W glocks get a bad rap, But I have carried a Glock 23 without issue for years and shot a few thousand rounds of the cheapest ammunication I can find through it.

Every time someone on my job complains about their off duty glocks jamming (Caliber does not matter), I clean their weapon as explained in the earlier post, properly lubricate the weapon and *Poof* the problem is fixed.  

1000 rounds is just enough rounds down range to build up some thick carbon in places you may not want it.  

This is just my experience

Voyager4520....you friggin rock!!!!

Thanks for taking the time to put that post together.
The HD vid on how to disassemble and reassemble the Glock was exactly what I have been looking for...I learned to do the slide last year but never took the time to do the frame. Now, I have three clean, dry, Glocks ready to go out and shoot again...Lots of crud in the trigger group.

G22 - has seen about 2000 rounds since bought new in 2001
G23 - has seen about 1500 rounds since bought new in 2004
G27 - has seen about 500 rounds since bought new in 2007

The G22 and 23 have seen 500 round days at Oregon Firearms Academy for defensive pistol I, II, III.
I have never experienced a failure of any kind with these firearms. In fact, we have to feed them snap caps and force jam (double feed, etc) in training to learn what to do should the need arise.

Now I'm gonna take them out and work them hard this weekend again
