Looking for some input on my jamming problem on my Glock 17. The picture below is how it always jams. It does fine with slow single shots but at quick rapid fire it will jam by about the 4th or 5th shot. I am using 147gr. because anything lower only makes it worse. I have used different brands, some are worse some are better but they all jam. Is this a spring issue or something else? Thanks for the help IMG_2296.gif
 
I had a G23 that I took to TR many years ago. The second day of class the weapon kept smokestacking like yours. I had one of those goofy Harts Recoil Reducers in it and it was hanging the slide up. After I threw that silly thing over the berm and put in an extra factory spring, it worked like a champ.

Did you buy your pistol used?:scrutiny: I'd replace the recoil spring thingy. Takes 30 seconds and costs maybe a dollar.
 
Yes I did buy it used, and it has an internal laser site which passes right through the middle of the spring. Do these laser sights take a different spring than the original?
 
You're obviously lying. Everyone knows Glock's don't jam. ;)

All kidding aside, I'd also recommend removing the laser sight and seeing if that makes any difference.
 
Concur wth short cycling/ slide velocity issue.

Another thing to check is that you are not contributing to the above (issue) by relaxing too much toward the END of the string, (last shot or two), and letting the wrist become a bit too soft. This can also occur at the end of a pleasent hour or two at the range when you are more relaxed...especially if you have a performance set up and ammo combo that is close(r) to the line on cyclng reliability. In addition, bear in mind that the polymer frame of the Glock has a slight dampening effect. You may well discover that the failure is due to a combination of very small insignificant factors. Correct any one of them and the gun becomes 100%.

The good news is that troubleshooting is extremely easy. The best approach is to hand the pistol to one or two ACCOMPLISHED Glock shooters for a few rounds down range before you start changing-out components.

Bingo
that might be the issue right there, my dad's model 19 had trouble cycling light loads with the guide rod laser, same problem as yours. but it was a simple fix, he reloads so he just loaded up a liitle hotter rds, and everything worked out just fine. the springs are heavier to protect the laser and the internals.

Take out the laser and try it stock

you can do that but i am telling you from personal experience that there are just a little hotter loads needed.

So If I get an original spring it won't work with my laser?
 
Just get the Crimson laser thingamajig or an M6 Insight Tech light; and replace the recoil spring with a stock one.

Well that would be all fine and dandy but its hard for me to just replace a $350 laser sight for another. I want to try everything with this laser first. thanks for the reply though.
 
My 1st gun was a Glock 17 bought in 1993. That thing was a jammomatic. Couldn't get thru 1 mag w/o a jam.

But, I knew that was unusual. And, I've owned 4 other Glocks since, all working 100%.

In your case, as everyone else said - take the laser out and put in a stock spring. Then, see what happens.

Im a rookie at Glocks and I bought this one with the laser sight already installed. I don't have the original so I don't know what it looks like. Will the original go over the laser? or is that not possible?
 
Muddcat,

Please reference my prior post. You do not need to swap components right away. Take a variety of ammo to the range and an OE guide rod/captured spring in your range bag. While shooting be sure that your wrist is locked on EVERY round of the string. If the issue is with the guide rod/spring or extractor, the Glock will let you know.

I'll wager that the good folks in Smyrna,Ga. will send you an OE guiderod/spring at no charge with a simple call to them for assistance.
 
This is a first for me i have never had my G22 jam but mine all stock but my sights . get rid of the laser that should fix it i would say (now watch the next time i shoot mine it will jam LoL)
 
Funny you should mention this problem... but a couple of months ago I was helping a local LEO with his weapon qualification... he was using a Glock G22with a laser sight and was getting stovepipes... his laser sight was a little oversized and was slowing down slide velocity to the point of causing stovepipes... replace the laser sight with a standard Glock recoil assemply and try the weapon out again...
 
With the number of guys thinking they know more than the engineers the factory guide rod set-ups are dirt cheap. I think the last time I bought some I got 3 for $20 shipped. These were essentially new guide rods with springs and all, and for that kind of money I don't see why it wouldn't be worth it to pick one up and try it, if the gun works at least you will know what the problem is. You can try a factory weight spring on the laser rod, if that doesn't work you can check to make sure the laser rod is straight and of the right diameter.

Those laser guide rods are all the same, whether it is for a g17, 22 or 31, and if you believe most the G31 and 22 need a much heavier spring. It could be that the laser maker buys into that BS and is springing them too heavy.

If I were you I would post a WTB ad for a factory guide rod setup. Pay postage both ways and I will send you one to try, at least eliminate springs as the cause.
 
Step 1 - Take out laser
Step 2 - Put in stock weight Glock recoil spring
Step 3 - Sell laser
Step 4 - Apply laser money towards gun school
