Jamming / Misfeed Question

[bone1]

I took a brand new Glock 17 to the range today and experienced quite a few jams or misfeeds. Probably about 1 out of 10 rounds would misfeed.

I haven't experienced this before, but since the gun is new, my first thought was that I wasn't loading the ammo into the magazine properly. I'm a relativley new shooter, so I'm not quite sure what could be causing this. Is the round supposed to sit at the very back of the magazine, or towards thr front, or does it matter? Any ideas?

I was using UMC ammo purchased from Big 5.

I always take two different brands of ammo out with a new gun.
Just in case I have an issue like yours, I switch ammo first, then the mag.

Probably the ammo.

Should smooth out after 300-500 rounds. Break-in period.

Also make sure you have lube oil on it. Not a lot required, but a little bit at the contact points where the barrel contacts the slide, etc. I've seen brand new Glocks have cycling issues right out of the box until the owner lubed it up.

Again, just a tiny bit is required. Don't over do it.

You also need to hold it with a very firm grip The recoil operates against your resistance and if you "give" too much, the Glock won't cycle properly.

No limp wristing on the Glocks

UMC FMJ I presume? (I think all the HPs are "Remington" branded)

[bone1]

Yes, FMJ.

So far, we have:

Ammo or magazine issue
Gun needs to break in
Need more lube (this is never good, in any situation)
Weak grip

No comment so far about the position of the round in the magazine, can I assume that it shouldn't really matter as long as the round stays in the magazine?

I'll try it with different ammo next time I'm at the range, and with more lube. Not sure when that will be as I'm expecting an addition to the family at any moment.

Personally, I have to say that a weak grip wasn't an issue. Other experienced LEO shooters had the same issue with the same gun.

I vote 'limp wrist'

[SubSolar]

Yeah, when I take some of my new shooter friends to the range with my guns, many of them jam the Glocks cause of limp-wristing. Of course, I have never had one malfunction in any Glock I have ever fired and neither have my experienced shooting friends.

-Lube
-Limp wrist
-Bad ammo

I shot my g19 straight of the box with no cleaning and WWB and didn't experience any jams. When you loaded the magazine, did you tap the back of the magazine to ensure that the bullets were situated correctly? Have you tried a different brand of ammo?

Clean your G17 and the next time you go to the range, get a couple different brands of ammo and see if the jamming persist. It may just not like a specific brand. If you are still experiencing jamming on different brands, you may be limp-wristing.

Have some with more experience with a semi-auto shoot the gun and see if there are any jams. If it is still jamming, go to the dealer that sold you the gun and have them look at it or call Glock.

Yes cartridge placement does matter inside the magazine. I always insert cartridges fully to the rear of the magazine, and after loading several rap the back of the magazine against the heel of my hand to ensure they stay back. Cartridges that move forward while loading can cause feeding issues.
