    Sometimes when I "slam" in a new magazine, the slide on my G17 closes unexpectedly. Did I lubricate something I shouldn't have?

    No. "Slamming" in the magazine relieves the pressure on the slide stop just enough that the spring draws it back down. When the slide stop spring goes down the slide goes forward. Don't overly worry about it, the slide Will pick up the top round in the mag since it is the magazine going home that causes the jarring.

    I'm left-handed, so my trigger finger is usually resting on the slide stop, so it's quite easy for mine to drop when completing a reload. Since my G17 has been doing this since about the early 80's and each time it picks up the top round, I've stopped worrying about it.

    Not uncommon w/ Glocks. In fact, it's a bonus "feature" to some USPSA shooters. :p

    My USP does that too, I wouldn't worry about it. So long as it isn't closing without grabbing the top round it doesn't seem like anything to worry about to me. I usually seat magazines relatively softly, so I didn't notice that 'feature' until a someone else was shooting it.

    It is a bonus for sure. Not having to rack saves a half of second. I can get off an extra shot in the same amount of time.

    If the gun was not designed to do that, there is something wrong.


    If this was anything other then a glock people would have posted to send it back/ gun smith.

    What about the people who have stated that their S&W M&P's, and H&K USP's do the same.....aren't they referring to something 'other then(sic) a glock(sic)'?

    Less than a year. Probably less than 2K rounds through it. It didn't start doing that until after I "cleaned" it, which is why I thought I might have gotten lube on the slide stop or something.

    This is normal. Don't worry about it. I have 6 Glocks and if you "slam" them hard enough, they all will do it. It does come in handy sometimes, IMO.

    If you don't believe this about the mags, go over to GT and ask it in the General Glocking section. Anyone that has any experience with Glock will tell you it happens. The haters will tell you it's broke. I have " a few" pistols. If I had to keep just one it would be a 2nd gen G22 that was a LEO trade in. It has been like a very accurate Timex. Takes a beatin and keeps on tickin. I know because I have purposefully not cleaned it before for several thousand rds just to see how it would act, guess what, still 100% reliable.

    I consider that to be a feature, not a bug.

    If any firearm I own does something it was not designed to do(and in this case it might be a safety issue) I will send it back to the manufactor or to a gun smith to be fixed.

    If the gun is known to do it, its not a malfunction, its a design flaw.

    Ahhh... so "If this was anything other then(sic) a glock(sic) people would have posted to send it back/ gun smith." really means "if it was anything other than a Glock, S&W, H&K or any other pistol, people would have posted to send it back/(,or to a) gun smith." Glad we cleared all that up. For a moment there I was worried you thought it was a Glock problem.

    If you get the right angle with enough force, practically any semi-auto slide will close when you slam a magazine in. Especially one that's had a lot of use.

    It's not a malfunction, it's normal.

    YEAH it happens with the M9...in a Battalion weapons competition...and it DIDN'T pick up the top round.

    My suggestion would be to go easy on it, maybe clean it again. The one time it does it without you wanting it to, or doesn't do it when you expect it to will throw a monkey-wrench in your routine.

    IMHO if a piece of equipment is doing something its not DESIGNED to do, then it is malfunctioning and needs to be fixed.

    Carry on.

    Slide lock lever

    Owning several Glock pistols, all 9mm, I have had extensive experience in what they do, and are not supposed to do.

    Glock trained Instructors were informed the "Slide lock lever" was for that purpose only, to lock the slide back on an empty magazine, and not to close the slide, as in "The slide release" designation of other pistols.

    The same Instructors were very vocal in this area, that is till the loss of revenue caused by after market manufactures came to the attention of the bean counters, that part was the extended slide release (not a Glock term) in one model production, the factory was so paranoid over this practice, they changed the angle of that cut in the slide that the SLL mated with, this caused the shooter to have to stand on this same SLL to close the slide by the outlawed/illegal/not recommended/ method of pressing down on the SLL.

    Only the sling shot method was taught.

    One of my older G17s slides would close even if you inserted the magazine so very gently, that it was not practical to leave that after market part in place, so I changed it with a new factory SLL, I now have to press down to close.

    The reason I did that, right or wrong, I want to be in charge of every function of a pistol that is used for IDPA and IPSC, but might be pressed in to a carry under shirt item.

    For you non armorer types to see the area of wear in question, and not taking parts off Willy nilly, remove slide, this removal process requires the go button to be pressed (trigger) please carefully ascertain the absence of live cartridges most diligently.

    Looking at the back edge of the SLL, edge closest to the rear of the pistol (a naked eye not being good enough for Old Guys,like me) use of a hand held magnifying glass is permitted, on an older, or much used pistol, the corner will be nowhere near as sharp as that corner on a new part.

    One pitfall of the auto close feature, if it does not happen when the shooter who expects it to happen, inserts a magazine, the tendency is to whack the offending mag base plate to cause the slide to close, a few times, not a good idea if 115g hardball rounds are in your vicinity, pointy end first!

    Your pistol is fine, it's just like many of the other posters mentioned. You will notice if you don't "slam" the mag in place, it won't happen. If it does with a "light" insertion, then you have an issue. I am a firearms instructor and Glock armorer for our department & we have been using Glocks for years now (first 17s & now 22s) & I see it all of the time on the range. As you use the pistol & wear the burs / sharp edges off of the slide catch & it's "slot" on the bottom of the slide, they start doing this. I have never seen a Glock not pick up a round when this happens. Can't speak for other brands. In the Glock firearms instructors school we were taught to rack the slide to release it due to the loss of fine motor skills under stress. Imagine trying to hit the very small & flat Glock slide lock when you are under fire, shaking, sweating, tunnel vision, ect. As you do in training, you will do when TSHTF. When Glock decided to make pistols for competition, they deciced to turn the slide lock into a slide release by extending it and adding a "bump" to make it easier to hit. If you use the "slingshot" method to release you slide, just make sure you do not ride the slide forward as you can slow it down & cause a malfunction.

    There is a mention of it in the operators manual for my USP.

    :)
