magazine failure to feed issues

I've got some questions about a failure to feed issue on my firearm.

I have a Glock 27 that, up until a few days ago, never had any malfunctions. A few days ago, I shot it with a Glock 22 magazine (15 rounds) that I had gotten the previous December. It malfunctioned three times. One of them was just a 2-second hesitation to load the round. On the other two, I had to rack the slide to get it to feed the next round. The gun has never malfunctioned previously; and after using the 15-round magazine once, I shot several 9-round magazines through it with no issues.

Based on these facts, the issue is most likely related to the 15-round magazine. My first question is: is it normal for Glock 27's to jam on Glock 22 magazines (it was my understanding that Glock magazines are one-direction interchangeable among models within the same caliber)? Second, what should I look for with regards to problems in the magazine?

Apparently David has stock in Glock magazines.

Yes, there might be dirt/detrius that needs to be cleaned out.

Yes, the magazine spring might be bad (not probable but possible).

The follower may be sticking simply because some lubrication is needed. Many folks never lubricate their magazines over the couse of its lifetime.

Have you looked at the feed lips? That seems to be where the majority of feed problems stem from regardless of what magazine for what gun platform.

But most likely your problem stems from the fact that you bought a Glock instead of a real handgun. (Just had to get a dig in on the plastic fantastic wundergewehr. It's almost a rule. :D )

stay safe.

you can clean it and see if it improves ... if not, toss it ... springs go bad ...
I'll look into that. I would hope that a bad spring isn't the issue, given that it's a brand new magazine (bought it in December; shot it for the first time this past week).

I did notice that, on two of the jams (the ones where I had to rack the slide), the bullet was not in the correct orientation. Instead of being angled upward, the jammed rounds were caught on the feed ramp and facing either level or slightly downward. Basically, it appeared that the spring had not pushed the round up far enough and quickly enough before the slide came back forward.

And, as to your last comment, I chose the Glock (generation 4, to be exact) for several reasons. It is easy to take apart for cleaning (I can actually disassemble and reassemble it blind-folded in about a minute). It's very simple to operate (i.e., there is no issue of forgetting to turn a safety off while in a high stress defensive situation). Finally, compared to most men, I have very small hands. The grip on a generation 4 Glock fits my hand perfectly. The grips on many of the "real guns" (1911, for example) just simply do not fit my hands very well. Also, I don't particularly like guns with a grip safety (it's an OCD thing; I don't like a grip that has a moving part in it; I like the feel of a nice, rock-solid grip).

This thread is false. Glocks never jam. Ever.
Indeed, I have put several hundred rounds through the stock 9-round magazines without a single jam. All three jams have occurred on this one magazine; and the jam rate was 20% for that single 15-round magazine (I used it only once that particular day).

Are you putting extra hand pressure on the mag because it is sticking out.
That is possible. Generally, due to my small hand size, my pinky finger rests on the 1/4 inch base plate on the stock magazines (for those not familiar with a Glock 27, the subcompact Glocks have space on the grip for only two non-trigger fingers; due to my small hand size, I'm able to rest my third finger on the bottom of the magazine). Therefore, it is possible that my pinky finger could be pressing against the magazine and altering its angle.

how many rounds do you have through the glock?
have you replaced the recoil spring??
I've put several hundred rounds through it with no issues. After using the 15-round magazine, I put another forty or so through it with no issues on the stock 9-round magazines. All three jams occurred within the 15 rounds I put through it on the 15-round magazine. I used the same ammunition type in the stock and 15-round magazines.

And, no, I've never replaced the recoil spring.

I have a G26 and a G27, both of which are gen3's, and though I don't shoot them very much, neither one of them have ever had any problems of any kind whatsoever. I installed a Pierce mag extension on both or their primary magazines to allow my shooting hand to gain a better purchase on the guns. In your case, I am leaning towards one of your hands contacting your larger magazine at the time of firing. I know I had something like this happen to my primary carry gen3 G23 (was shooting from a rest once and the recoil apparently caused the magazine to seat deeper into its well causing a stovepipe). In particular, I would bet one or both of your hands is causing the larger magazine to bend towards the backstrap at the moment of firing. This would be a natural thing since recoil pushes the gun up and back.

The OP must be limp wristing.:lol: We know only SNS jam. :banana:

Honestly it is probably the ammo or a nick in the feed ramp. Try different ammo, polish the feed ramp, THEN look to the magazines. If all else fails use the Glock warranty. If they are like Hi Point(SNS) they will fix or replace free of charge and give you new magazines to comp for the shipping.

OR just buy a 3 Hi Points for the cost of one Glock.

The only FTF issues I have seen with Glock 27 and 17's is from limp wristing. In both cases they were girls. The first one has gotten lots of training and now fired a couple thousand Rds and no longer has the issue. The second I'm working on. Not to say there can't be other causes. But they are very reliable feeding arms.

DOH!

It it runs without any issues with one mag, and jams repeatedly with a different mag, it's the flipping mag :banghead:

Just thought that I would point out my Ruger Super Blackhawk has never had an ammunition feed issue. There was another thread, now locked about the suitability of one for an OC piece. Hurumph!

I was thinking about that, but I decided to be a good boy and not bring it up. I missed that the issue was with one magazine, the OP should take it apart, clean it, polish the bearing surfaces, lightly lube it, and put it back together. Personally I do not oil my mags, I polish them internally, and wax them with Johnson's paste wax. Oil attracts grit, which will bind a mag.

I use either a quality dry lube (Hornady's One Shot) or a good silicone spray (CRC Heavy Duty). Neither of these will attract dirt, lint, or debris in and of themselves and do work to keep the internal movements slippery.

+1

I lube the follower and the internal bearing surface with One Shot.

I do, however, lightly oil the spring and wipe it dry. That alone doesn't attract much of anything.

I use stainless mags/followers, but the spring is still susceptible to corrosion, and I've never been impressed with One Shot's corrosion prevention abilities. Silicone spray probably works well in that regard, but I've never convinced myself to like the stuff.

since you said it was new i would check and insure you in fact got a g22 magazine and not a g17 magazine. they can be easily mixed up just by glancing at them
