    I got back from the pistol range today and had my workbench lit up with my new LED fixture and saw this:
    20181015_000034.jpg

    Those 'dots' inside the grip are from the blowback I believe during ejection.

    Correct me for bad terminology - but those dots of unburned powder are coming out of the magazine!

    Somehow the gasses get into the mag and blow out the holes where you can see how many rounds you have left. This is the first time I noticed this - but it took those LED lights to make it pop out to see well.

    I imagine that the spring and follower gets bathed in hot blowback.

    Do you think this is the only place those gasses can get out since I plugged up that grip-void with a plug - you know: the hole behind the magazine....!

    It’s common. Gasses go everywhere. Mine is not plugged and I have that. It’s even more noticeable in the guns I shoot suppressed.

    Never seen that in 25 years of running Glocks, over 20 different models, and over 400,000 rounds. What's your load? Plated bullets tend to have more blow by than any other construction type.

    Never seen either. I saw that photo and I had to double-take; like, "what's the back of the magazine still doing in there?"
    I do know that stuff wants to go out the bottom of these pistols. Maybe that "unsupported" portion of the chamber/case is a bit more generous than others, allowing a bit more gas to flow through?

    You haven't seen a dirty mag till you run one in a blow back gun.

    I'm shooting Selliers & Bellot (sp?) 180 gr. FMJs. This was after @ 100 rds. and oh!.. I also shot about 8 HPs, unk make or bullet weigh.... I didn't look... my buddy just tossed me some of what he was shooting to try them. I return tossed all but 7 or 8 of them back to him.

    My Glock 20.4 didn't like the HPs very much. They were in a factory box, so I'm sure they weren't reloads.

    I didn't notice any heavier or greater amount of junk in the pistol from times in the past, somehow I might've missed this buildup before..... although I don't know how... 'cause I tend to be very OC on my tools, guitars, vehicles and firearm.

    Have you any pictures of that?
    Is it a carbine conversion type-thing? Just interested, that's all.

    Agreed. I ran a hair over 5000 rds through a suppressed MP5 without cleaning it.

    Everything was stinking chunky filthy.

    What motorcyclist said. Uzi mags get dirty, as does the lower receiver, but they most always work. If a follower becomes sluggish you can get a FTFeed (empty chamber or misaligned round) due to bolt not stripping the round correctly. Weak spring will do same thing. Maybe twice in couple decades had to take an Uzi mag down for crud removal and/or spring replacement. Easy to assess both binding and spring tension with a pencil. Have never needed to take a Glock or AR mag down...except out of curiosity.

    The Uzi .22 kit Vector mags are another matter. They come down about every half dozen mag dumps, and I hose down the lower receiver at intervals. Took all my Ruger 10 rd mags down last year for the first time, but they weren't too bad.

    Yeah.... I'm not worried... I'll clean it all anyway. I just never noticed it until the new LED bench light.

    Mine get the same marks on the inside of the mag well. I also use WWB though and that stuff can be a little dirtier than other ammo. Still runs fine in all of my firearms

    No problem shooting all day.... it seems to be like an AK in that it can run under adverse conditions. Just what I wanted and need.

    Wasn't there an Israeli pistol that had these same qualities? Dunk it in mud, drive over it, rack it and shoot.

    Ripped 216 through my X today. I remembered your post, so I looked up in there, and yes, there are seventeen little soot smudges along the back wall of the mag well. Winchester white box ammo.
    Sun light reveals it pretty well also.
    Point taken. Gonna keep them clean henceforth.

    I'm glad that worked for somebody.
