Ive had a G27 for a few months now, and I love it! I keep reading (mostly in GD) that glocks explode and are nothing but hand grenades. I know countless people who have had glocks for years and none have had them blow up. What is the straight scoop? I did a quick search, and I didnt get anything that was of substance. |

Load of crap. All firearms can malfunction as well as the ammo can be a problem. I have 5 Glocks and the only thing I stay away from are lead bullets. There may be some substance to the idea that the rifling on the Glock shaves the lead and increases pressures. If you reload, use jacketed or get yourself an aftermarket barrel. |
The peculiar rifling on the Glock (called POLYGONAL RIFLING ) **is the cause of this. Apparently it retains lead pretty badly,starting with the first shot of a lead bullet, causing subsequent shots to deposit more lead... leading to very high pressures. Stay away from lead bullets and you'll be OK. My Baby Desert Eagle has polygonal rifling and I shoot only jacket bullets in it for this reason. **The Wiki article I link to here has an article about leading in polygonally-threaded barrels that suggests that Glock is especially prone to leading due to their unique barrel. YMMV. |

the glock is one of the most prolific designs in the last 50 years. a few have malfunctioned and hurt people. glocks are "plastic" and kind of like pit bulls are somehow seen as more dangerous than other breeds. even though you are more likely to be bit by a Labrador it's no news worthy or cool to mention. i have a 19 and like most owners it's by far the best gun i own. i have custom 1911s and other super high end custom shop guns. but the old 19 is my tactical staple gun and like an AK47 or an 870 it's my go to gun. shoot with confidence and ignore the haters. |
| Any gun will explode of you feed it shitty or over pressure ammo. Squib a round and then put in a triple charge after it and see what gun could survive it. In a hot round like the .40 S&W, I wouldn't call the unsupported bottom of the chamber a good idea, but if you're not reloading and overworking that part, it outta be okay. Almost all Glock kBs can probably be traced back to bad ammo. |

It comes mainly from the .40 Glocks and people's use of dog shit reloaded ammo or over pressured/improperly died rounds. There are a few reasons that you hear more about this happening in Glocks more than any other firearm. The biggest reason is that there are so many more Glocks in circulation than any other handgun. The other reason is that Glock .40's are truly not designed for reloaded ammo. The reason for this is the partially unsupported feed ramp. It is designed this way to increase feeding reliability. If you look at 95% of KB!'d Glocks, the casing that caused it is 99.99% of the time A: reloaded and B: blown out at the case rim next to the feed ramp. You may notice that you won't find a single manual that comes with a new firearm that does not say: "Intended to fire new manufactured ammo only. Firing reloaded or remanufactured ammo will void your warranty." |
| Ok I will tell my real personal experience with a squib round. It was in 2002 and i was a newly hired police officer going through handgun qualification. We were practicing failure to fire/tap and rack with dummy rounds and live ammo. I was shooting American Eagle 180 gr. .40 out of my brand new Glock 22. when I hit a dummy round we would tap and rack to a live round. I was new to guns at the time and I felt a low recoil round go off and did not remember seeing a round go down range, but being new I did not know better. The round had lodged in the barrel and I fired another round right in to it. I felt it but once again was not thinking. After this every time I hit a dummy round it was getting harder and harder to rack the slide. finally the gun just locked up with the slide open and it would not budge. The armorer looked down the barrel and did not see anything wrong and we could not figure it out. Took it back to the PD and the armorer had to put it in a vise grip and hit the back of the slide with a mallet several times to get it unstuck. Took the barrel out and it was blown. four very large cracks and bulge in the middle of the barrel. We estimated I shoot about 60 to 70 rounds after I noticed the soft recoil and the gun started having problems. If I was on the street at that time in a gun fight It would have been able to shoot all my duty ammo. I was still hitting the target center mass at 10 yards too. The gun and barrel were cent to Glock and all they did was put a new barrel in the gun. Glock said the slide was ok no damage at all. I still have it to this day. It has well over 10,000 rounds through it. I firmly believe if I was carrying anything less I would not have a hand or be seriously wounded that day. I have never heard of this happening to anyone else. I wanted the barrel but Glock did not send it back, " Damn" |
Yeah, I can tell you what happened. Portland PD claimed that they were using factory Federal ammo. Glock offered to pay for one of Portland PD's so-called firearms experts to come to Smyrna with the two Glocks and observe Glock/Smyrna's evaluation. Portland PD declined. They later sent the G21s to White Labs for testing. White found that the KBs were the result of overpressured ammo, of course. Didn't hear much from the Portland PD's "experts" about the White Labs testing, did you ?

| Yeah I was lucky, I know that in 2002 and 2003 we had a lot of problems with ammo mostly with Gold Dot duty ammo, Gold Dot had changed some of there casing slightly and the FBI found out a few lots were bad, but we never had problems with the American Eagle practice rounds. I think I just got unlucky with a primer only round or something. i love the Glock and this made me a true lover of the Glock's. I'm a Glock armorer and was one of the departments firearms instructors.. In five years of instructor schools and training officers I have never seen a major malfunction that was not related to bad ammo with the Glock. |
Welcome to the forum, FD-P099. Thanks for your input!!!

I'd steer clear of others' reloads. However, all I shoot through my Glocks are my reloads. So far, after tens of thousands of rounds, no problems. |

I had one of those E series framed Glock 19 Cs. This was way before the famous "Glock Upgrade" instead of being called a Recall. I have seen pics of the rails snap off etc and still work...but mine the frame molding was also bending back along with the rear frame rail. I called Glock and they said impossible. Took it back to my dealer and he said holy shit! Let me traded it back in and then 6 months go by before I hear the talk of sending it in for Frame replacement from Glock. That was a manufacturing defect. I also purchased a Glock 31 in .357 Sig. Was breaking it in at the range with Speer Lawman ammo and the gun seized up. Half a casing ejected while another round was loaded into the chamber where half the casing was still stuck. Took a vise and mallet at the range to free it with a live round stuck inside it. Scared the poop outta me. Sent back to Glock for a check up and no bulge in barrel or anything. The gun had deep gouges in slide...Glock said that was normal and called it "peening". Shooting it took some good sized chunks out of both sides of the slide. Shot it many times since and it has been fine but I still feel scared of my gun. I carry H&K for protection now. Zero problems with HK after having 2 problems in two different guns with Glock. |
Contrary to Glock Armorers' School (but what would you expect), the use of a stronger recoil spring will mitigate slide peening in .40 and .357 Sig Glocks, and any other undersprung Glocks. Does anybody really think that a G20 should use the same recoil spring weight as a G21 or G17? Yeah, Glock engineers do. Wonder why? Hint: Has nothing to do with mechanical efficiency, but, rather, manufacturing uniformity/ease. |
