How does the Glock stay accurate?

    I'm sittin here staring at this Glock 30 I bought recently. I'm shakin the end of the barrel, noticin the way the chamber section of the barrel locks into the slide, and generally just comparing the design to my Walther PP 32 and my 1911's, in regards to how long the inherent accuracy will last and what parts would need replacing over time.

    So, am I correct in assuming that this Glock is gonna need a new slide/barrel combo over time? I don't see any other replaceable parts that would contribute to the longevity of it's accuracy. Any of you Glock owners with high round counts have to replace either of those yet?

    Another quick question and I'll let ya go. I've got 5 mags for this beast. 4 10rd and one 9rd, which irks me to no end. The 9rd has a body with 10 witness holes, so I assume it has the capability of holding 10rd. Is it just a matter of cutting the spring down to get it to hold 10rd, ya think?

    A Glock barrel (and all modified Browning guns) has a lot more locking surface than a typical 1911, and no rounded lugs to round off or chip. It also has a locking section that has much more surface area than a 1911 link, and little lateral play due to the square profile and slide. As Glocks are well known to retain their new accuracy for a lot of firing, I doubt it's a problem.

    From what I've been able to tell, the lockup on Glock pistols is REALLY good, that barrel has even less play than a Sig's does in battery.

    That's what I suspected - more locking area. That's a big chunk of steel lockin that chamber to the slide, both above and below. I only got to thinking about longevity when I noticed finish wear on the front of the top locking area.

    I guess I like this dang thing. That's sayin somethin, because I've been tryin to hate it and scrutinize it with every shot and every teardown, and there's really nothin bad about the design whatsoever.

    Hell, she even looks good.:D Can't say the same for them full-size Glocks, but a double-stack compact just looks mean.:evil:

    Oh, don't tell my 1911's I said that. They're sleepin in the safe, if they hear me I'd hate to suffer their wrath (flying plunger tubes, sticky mags, front sights flyin off, wobbly links, chipped locking lugs, oh it'd be brutal!)....:uhoh:

    Al, I've shot my G19 at 100 yards. It's not really much fun. I have other 9mm pistols that will hold center mass at that distance, and a .45 that is like dropping motors at that range.

    isaidme, anyone who bashes Glocks are probably new to guns and are pretty wet behind the ears.

    Even if you hate Glocks......you should respect the fact that they have broken barriers that other pistols could only dream about.

    On top of that....No other pistol in the world has a more positive out-of-the-box reputation than Glocks. Which is why most anti-glockers can never put up a good argument without sounding stupid.:neener:

    Al, she couldn't do 100yd clamped in a shipyard benchvise with an elephant sitting on top of the muzzle, a mouse pulling the trigger, and a 30x scope, not with 230gr ball @ 850-900fps anyway. Somebody's on drugs.

    I shoot my G17 and G21 @ 100 yds frequently. Don't have too much trouble hitting fairly small targets consistently. Most of my 100-yd shots with pistols are from the bench, not offhand.

    I recall you asking (or someone) asking. I've played with one at 100y, used S+B 230 grain. Once hold over was figured, it was a good area pistol. Make someone take cover ASAP. Just didn't have the sight radius to work well. Front sight was wider than the target.

    No, it's just that the mags are VERY tough to load to the last round. I have a bunch of 10-round Glock 21 mags and had to force most of them to accept the last round. I was told to load them to capacity, then let them sit for a few weeks - this is supposed to make them easier to load. Supposedly this is to avoid legal problems if you were able to load more than the government-mandated number of rounds.

    My G26 is an ugly black block, and I highly recommend one to anyone that asks.

    Oh, lemme try that thing at 100, I'm starting to get ok with that plastic sproinger trigger thingy. Got some nice hits shooting my 17 at 75yds this weekend. Steel gong a foot sqaure, but I did have one group that was two touching and a third an inch away. Holding dead on with some light fast 9mm.

    All of the steel in a Glock handgun is treated with Tenifer (titanium nitride that actually permeates the metal) which gives it one of the toughest surfaces found in the world of metal. In other words, the chance that you will need a new slide or barrel in the life of the gun is 0, unless you manage to blow it up with an overload.

    Navy joe, I was making 100 and 130yd shots with an ol' Hi-Power I had back there, with Winchester white box 124gr and minimal lobbing. Them 9mm's are some accurate little suckers, no doubt your 17'll do it.

    I don't think you'll be needing to replace anything to keep that gun accurate...ever.

    I've shot my G34 9mm at 100 yards. No joke, I was actually able to keep 70% of the rounds in the black on a NRA 50 yard slowfire target. That's probably good for minute of torso. Out of three magazines, think I had 22 or so in the black, another 6 or so in the white, and 2 off the paper.

    Dunno for sure. But my Second Gen G19 was manufactured in 91 and it apears to have the same slide and barrel. Dont know how many rounds the previous owners have put thru it but Im up to 3,000 rounds and its still far more accurate than I am. One ragged hole at 15 yds from a bench rest.

    Yep. You know that little slip-over thing they ship with the new guns to help load rounds... The first few times I loaded my mags, I couldn't even get the last one in without using it. Now I can at least load it without using that thing, but it still takes some extra effort.

    Rally Vincent sez:

    Nothing like a little pre-emptive insecurity eh? What "barriers" do other pistols "dream" about? The hype barrier? The kaboom barrier? The frame recall barrier? The ballistic fingerprinting barrier? The phase 3 malfunction barrier? The limp wristing barrier? The $550 for a $75.00 pistol barrier? Please, do tell. Glock fans use the company's circus trick gun rag ads like a drunk uses a lamp post--not for illumination, but for support, because they seemingly feel they have to justify or evangelize their belief in a pistol many people hate for valid reasons. Glocks are okay, with a retarded grip angle, and a disingenuous "safety system," but they ain't all that.

    I can think of many pistols that have just as good out-of-the-box reputations as Glocks. However, unlike SIG, HK, or Beretta, Glocks do take the negligent discharge crown. Revel in your adequacy. People who don't like Glocks may seem irrational to you, but irrationality is in the eye of the beholder.
