Have a G26 from 80p builder & i think i finally found out whats going on after alot of research.So when a round is chambered & shot the spent shell casing is hitting the next round in the mag right @ the lip before the lead.so i cant get rid of the casing unless i drop the mag.It stops halfway & cant force it back.Tried a factory Glock mag & a magpul mag as well & both do the same thing....has anyone ever run into this before & is there even a fix??
 
Never use Live Rounds for op test sir šŸ™…ā€ā™€ļø Safety 1stā€¦head over to Amazon to purchase some snap caps šŸ‘ˆšŸ¼ Link.

@GSW10 should be able to give an answer to your issue. But heā€™s on leave right now.

However, Iā€™ll give it a shot. If I understand your post. The Glock and p80 are having the same malfunction? Iā€™m leaning toward the problem is with your mags not the weapons.
 
Sorry i shouldve said thats not me on the video just a reference.I have 2 19 mags & 2 26 mags & all 4 of them do it.2 OEM & 2 magpuls,all followers seem fine.I do have +2s on the bottoms of the 10 rd OEM do u think it would make that much of a difference?My snap caps cycle fine,they are a little smaller & alot smoother tho, no lip between case & lead
 
The first thing I noticed in the first video is that he is riding the slide. I think he is inducing a misfeed when he does that. I see a LOT of newbie (and not-so-newbie) gun owners guilty of this habit.

STOP riding the slide! Pull it back and LET IT GO. "Slingshot" it.

The other possibility is the ammo is just not compatible with the gun. Though Glocks can pretty much eat anything, there can be some exceptions. Furthermore... Polymer80 builds are NOT Glocks.... especially if the slide and barrel are aftermarket. So, the feed path may be a bit different (eg. the feed ramp to the chamber).

But, yes... function test with snap caps only until after you've done safety testing and test firing at the range.
 
i've read can be an issue of not holding the gun steady enough.
The cycling issue is most likely not a firm enough grip or anticipation of recoil.
Glocks are designed to be racked and then carry fully forward into battery on their own... not to say it isnt an issue however, if it will travel to battery on its own and there are no other visible problems the best thing would be to shoot it... a lot... you may be surprised how much things smooth out once you get a couple hundred round run through them and they have a chance to tool themselves a little... or if not or if still in doubt you could get it looked at by an armorer.
Watch the video on lubrication,
also take the slide off and see if the recoil spring sits correctly inside the slide, at times it can come off and jam.
Take it to a range, follow procedure put1 i round in mag, put 2 in other and go from there.

All good points!
 
I had this type of issue with a couple of 26 builds I did. Not sure if it's the same issue, but I found they cycled fine if I used True Precision barrels. Other aftermarket barrels would hang as shown in the video.

the first clip is OEM Glock, its suppose to work without any changes.
 
I built 2 940SC G26 guns. Both have Alpha Shooting Sports barrels and slides, no OEM parts, and single spring RSA's. They both are ultra reliable.
If you have used a slide and barrel from different suppliers that have tolerance/timing issues, that can cause this issue. Also, excessive parts drag between slide and lower can screw up timing.
I seriously doubt this is a mag problem. I agree with bciChild, you need to go shoot the damn thing.
Also, no sissy slide releases. Lock the slide back, insert your best mag, and drop the slide full force with the release.

I see this a LOT. It's a peculiar thing, but I guess folks are naturally-inclined to "baby" valuable things. But, yeah... it's actually quite important to let the slide work the way it's designed to work. Pull back and let'er rip! Or drop the slide stop release and let it fly.

Riding the slide is much more likely to induce a malfunction aka "jam." Not something you want to happen if the SHTF.
 
Zeffer p barrel w 80p upper.Bought all in the same day/same supplier...This is not me in the video.I do send it when i rack.Just put some rounds thru it & different ammo & it worked better ,didnt get stuck on the way back but did have it jam up a few times feeding..Im a newbie but 4 some reason i believe that the 1/2" movement of the barrel may have something to do with it.I was told others have alot of play in their barrel but my 19 & 26 dosent come close to moving as much.Didnt have much time @ the range & worked more w my 19 which is a weulf slide(complete)& that eats anything i put in it.Should i maybe move up to a 20lb spring?
 
Just wondering what different ammo you have tried. I have a couple of guns that have tight chambers and have trouble with some ammo. Take your barrel out, clean it and try dropping a round by hand into the chamber and extracting them with your finger tips.
The rounds that drop in easiest, and extract easiest by hand should cycle more reliably.
It's worth a try.
I don't think a heavier spring will help unless your gun won't go fully into battery when you drop the slide.
 
Lonewolf 9mm & Blazer 9mm both 115gr.the lonewolf shit is either steel or alum jacket & blazer is brass

The blazer ammo got stuck on the feed ramp & i had a ftf & wouldnt go into battery thats why im thinking heavier spring??

Not sure if this matters but....Post in thread 'Barrel play' Barrel play
 
This isn't terribly uncommon, the big problem is P80 changed their grip angle, making it more perpendicular (straight up and down) than Glock's highly swept-back grip. This alters the angle of the mag too, and pushes the rounds up more at the front. Now we know WHY the problem exists, but as for finding the fix, since MOST of them don't have a problem, can be trickier. I want to say this is more common on the Sub Compacts too, from what I recall from MGB's Forum.

I would suggest making sure your barrel is properly fitted to the slide, and NOT sitting too low. If the barrel is low at the back, so will the cartridge being extracted from the chamber be. And it is more likely to hit the next round in the mag.

One other thing that might help, load your mags to full capacity, let them sit for several days to 'break in' the spring. You may also have to adjust the feed lips of the mag -something I have yet to do on factory Glock mags- to keep the cartridge from pointing up too high in the front -unfortunately it is really easy to overdo, then you will have your ammo catching on the barrel's feed-ramp. Yep, this one can be a PITA to fix for sure...:confused:
