glock problem
 

put a aftermarket barrel in the glock

so I took it out and it will need a ramp Polishing, round hanging up once in a while.

The other thing that has me baffled is when shooting the mag drops out
not all the time but every once in a while, never happened with the stock barrel.

Re: glock problem
 

which glock is it?

WOW !!! That's good to know. I was just about to buy an aftermarket barrel. Can you elaborate on brand of barrel as well as caliber???????????

Thanks

Re: glock problem
 

Most issues with Glocks begin with people sticking aftermarket stuff on them.

Re: glock problem
 

If I may ask, what model Glock?

Aftermarket barrels usually have tighter chambers and may have problems feeding some flat-nose fmj or wide hollow points. If reloading, you will need to check each round for correct case and overall length, as those tighter chamber tolerances are less forgiving. Polishing the feed ramp should help some, but in the end you may have to limit your ammo choices to more rounded bullet profiles (Hornady XTPs).

Heavier aftermarket recoil springs increase slide speed and can cause feed problems with lighter loads.

With some models/calibers (like with my G21 or G22), a full mag is a little difficult to lock in. If that is the problem, try loading one less round, as there is a lot of spring tension to get that last round in. Mag should "click" when fully inserted and locked-in.

Also, make note of where your right thumb is when firing, in case you are inadvertently depressing the mag release button.

Good Luck, SC

The real question is what aftermarket barrel? KKM and Jarvis barrels should run 100%. I also download all of my pistol mags by 1 round and AR/M-14 by 2 rounds for the above mentioned reasons. Bx3

Re: glock problem
 

this I think is 100% right.
I dont know why people rush to 1911 their glocks.
Its a battle pistol with tolorances made for battle.

It works......why mess with it?

Re: glock problem
 

Glock 20
lonewolf 6" barrel
lonewolf S/S rod and spring

have a few glock 20's was setting this one up
for hunting and to shoot lead

now myself I don't like to add to much aftermarket crap
on most of my stuff but I now have 5 glock 20's
and trying to set this one up for hunting and some lead.

when the mag dropped out was shooting both 180gr and 235gr,
but had the lonewolf barrel and spring, have about 2000 rounds though the glock I had and never had one feeding problem or mag problem.

I just can't figure why the spring or barrel would make the mag drop out.

Re: glock problem
 

Check the magazine catch on the pistol.

Did it do it with multiple magazines?

Anything different? It's winter, were you wearing gloves? Any chance you could have inadvertantly depressed the mag release during recoil?

Re: glock problem
 

I am running both a G20/29 with KKM barrels - 100% reliable to include standard and extended lengths for both. It would be safe to say that if the reliability/mag problem is only happening with the lonewolf barrel, then the problem is the lonewolf barrel. Sorry...but if it makes you feel any better, I have a box in my garage (a very expensive one) full of crap that I have experimented with on all types of systems that worked less than expected. Bx3

Re: glock problem
 

My G20: KKM 5" barrel, Wolff 22# spring and steel guide rod, 10 and 15 rd mags. It feeds any factory ammo. Never had mags drop out, but curious if any of your other G20s do this?

Weak/defective mag release spring? Hard to say without looking at it myself. Maybe go back to stock configuration, verify reliable function, and ADD one component at a time until you induce a failure. That may help you isolate the problem.

You could also put those aftermarket items on one of your other G20s and see what happens.

As far as feeding goes, if you are loading Double Tap or other hot ammo, you might want to play with different spring weights to get the right slide speed.

Re: glock problem
 

I concur with SC.

ESPECIALLY the part about taking all the aftermarket parts off, putting it back to stock and making sure there is nothing wrong with it as a stock pistol.

IF that's the case, add ONE part on and then shoot it. Add the next part. And so on and so on.

You WILL find the part that is doing it.

Or, try this on any of your other four Glocks. It should be something simple.

Don't understand the mag dropping out. Unless it wasn't fully inserted in the first place.

You would have to override the spring weight on the mag release (not THAT hard to do, but still) to get the mag to drop free.

On the UP side, as least you have the 'drop free' mags. I'm assuming Glock mags.

IF NOT, let us know if you are using an aftermarket magazine. Every change could make a difference.
