Gentlemen,

What (if anything) is wrong with my little plastic wonder gun. It's a Glock 21 and I have only shoot it twice. I have never owned a Glock before, but I do own several other handguns and have never noticed a gap between the frame and slide quite like this.

The first time I took it out, I didn't notice the gap, than when I went to clean it after the first 50 rounds I saw the gap after reassembly. I should note that the second time I shot it, it looked as it did in the pictures and functioned flawlessly, so I'm thinking it is more of a cosmetic issue than anything, than again....I don't know, that's why I'm here.

Let me know what you think and thanks.

Yeah, normal. You'll notice your slide is connected to the frame by 4 little tabs of metal embedded into the polymer frame which mate to the slide rails.
 
If you look closely when you have a loaded mag in the pistol you can see the first round of the mag from the side view of the gun. Ahh good old Glocks.
 
From what I've seen, this is normal. In general, Glocks have pretty sloppy fit, which is probably not surprising considering how much they cost.

Yes it is. It's a MAGICAL Glock! I guess my point is the Glock's are designed to be a cheap and reliable service gun. Thousands of cops all over North America use them and I have not seen a "My Glock failed to fire" thread here yet.

I never said Glocks were not reliable. I simply pointed out the fact that they had loose tolerances.

And what's really amazing about them is how despite that sloppy fit, butt ugly looks, econo production costs they still go & go for thousands upon thousands or rounds. At least the G22 .40 cal I've been shooting since 1995 without one hic-cup has. :eek:

I don't think it's really all that surprising. It's a well known fact that all else being equal, a gun with loose tolerances would generally be more reliable than a gun with tight tolerances. That is the reason why older milspec Colts seemed to function much more consistently than the modern generation of "match grade" 1911s that require lengthy break-in periods, heavy lubrication, and magazine/ammo combos that the gun "likes" in order to work properly.

Making a reliable pistol with sloppy fit and loose chamber is not all that hard. The downside, of course, is that you are losing accuracy (due to poor fitting) and increasing the chance of case failure (due to oversized, poorly supported chambers). IMO, the true test of engineering excellence is building a gun that is both reliable and built to precise specs.

I don't necessarily argue with your logic above. What I can't explain about my old G22 though is despite the genuine sloppy fit some of my double taps almost go thru the same hole sometimes. :redface:

Your G22 sure sounds like a keeper. An average Glock is typically capable of "combat accuracy" out of the box, from what I've seen.
 
Firing slow deliberate shots at 10 yards often yields a single hole group with a full mag or more. Accuracy is a function of the shooter, not the equipment. I watched a buddy school a guy with his own 1911. A Norinco at that with combat sights(the nipples) and some crappy reloads. Its not the gear that makes the difference, its the shooter.

Well I kind of think it's a bit of both.
