Good post king. For the sake of avoiding an argument ill just go ahead and give you the win. I dont want to start anything nor do I wish to spread misinformation around to anyone. Trust me, I know I dont know a lot about handguns, I dont mean to steer anyone wrong. All I wanted to say was that I like glocks. I got off on a tangent about crap ive read, heard, or partially experienced. Not 100% facts. For that I am sorry.

XtremeVel said:There is really nothing stated above that I would disagree with, as long as we are talking about a specific caliber or two. I have owned and currently own SEVERAL Glocks. I will state though I recently did make a decision to get out of (1) caliber, thus leading me to trading (3) Glocks off. I traded them for (3) Glocks in another caliber. Also, I will admit this chamber support issue did play somewhat a part in my decision due to the fact I am a reloader and also enjoy shooting lead, but it was not the biggest issue. I actually had larger issues with this caliber than the support issue.
XtremeVel said:I would also like to add (1) point not mentioned before. Since I own both Glock and XD's, I will say I have come across the rare exception where the not so tight chamber does APPEAR to have an advantage. When I load and shoot the 200 gr .45 SWC with the sharp shoulder, the Glocks will eat that all day with the OAL anywhere from 1.22 to 1.25. The (2) XD-45's will only function with the AOL at 1.25 in both my service and tactical. This is the pet load I shoot the most. I find it to be very accurate and leaves such nice, round holes in paper.
XtremeVel said:In summing up I would say that to many Glock owners, the unsupported issue is for the most part, only a issue if something bad happens to them. At this point, I have never had any issues, only have found them to function fine and I shoot mostly only my reloads. By mostly, I would say easily over 95%.
XtremeVel said:As for downplaying the significance... Again, in my mind this has to do with what I have found so far. If the day ever comes that I have a KB and I feel that I did my part with the load, I will probably not only get rid of the Glocks, I will probably run away from the polymer frames... It all comes down to what I have seen or haven't seen.
Yes, it does seem to be a couple of specific calibers.
.
I'm surprised the XD45 will run SWC's at all. It isn't a chamber issue. There is an issue with clearance in the XD45s where the extracted case will run into the top round of the magazine causing a very interesting malfunction with SWC's. There isn't any issue with ball or hollow points but the shoulder on the SWC can catch so hard that it can turn the next cartridge nose down in the magazine. Here is a link to a rather lengthy thread regarding the issue.
The Continuing Mag Problem, Part2 w/Pics - XDTalk Forums - Your XD/XD(m) Information Source!
I've never tried SWC's in my 45 tactical. However, the issue seems to be much worse in some than others depending on machining variances. Some will feed SWC. The closest I have come to trying is I know that I can slowly hand cycle empty, unsized brass without issue. I may try SWC at some point just from curiosity.
This issue was actually addressed in the XDm45. There were changes made to the slide and breach face to solve it. See post #226 on page #6 of that same thread for details and pictures of the differences. I recently picked up a XDm45 as well. I like to see manufacturers actually address their design issues with successive generations rather than just rails, texture and finger grooves.
.
That is natural. It is easy to be disinclined to worry if nothing has personally happened. What I'm saying is really just commentary on the design. I'm certainly not saying anything close to "If you buy a glock it will blow up in your hand."
.
I just hate seeing it swept under the rug as if there is no difference between a fully supported chamber and a oversized, under supported chamber. That is all.

As for the "unsupported Glock chamber" thing, we could have a whole thread just on that topic... But for the sake of brevity, I can boil it down to one word for you: MYTH. The kaboom problems come from people who don't pay attention when reloading and use weak brass, or overcharge their ammo. Normal, in-spec ammo does not cause problems with Glock pistols. To satisfy all the people complaining about the "unsupported chamber," Glock recently redesigned their chambers. Observe:
Original Glock barrel on the left, New Glock barrel in the middle, and Aftermarket "Fully Supported" barrel on the right. Not much of a difference between the New Glock and the Aftermarket, eh?
Now look at this picture, which shows the OLD Glock design. Substitute in the NEW Glock design, and compare it to all the others. It's exactly the same as all the other pistols! The only two that "fully support" the cartridge are the Springfield XD40 and the USP 40, and to a slightly lesser degree, the Steyr M40. I guess anything else is going to Kaboom on you? Yeah right...
It's not a problem, just a persistent myth.

I once recently tried this in a G32 and saw it does happen !
really? I chamber the same 2 rounds, (1 in chamber 15 in mag). When I put my gun away I take out the one in the chamber then put the mag back in for safety and quick use if needed. How should I remedy this? Keep changing bullets around. Seems like a lot of work lol.
I would agree, but can only speak to (1) first hand. I saw enough back a few years ago when I ordered 5000 once fired rem UMC cases from a place I have always been happy with. What I found was pretty near 10% would split from the mouth of the case clear back to the web in the factory G22 bbl. The problem was eliminated by throwing in a KKM bbl with a much tighter chamber. Actually, .008 tighter ! Saying that though, I still don't put 100% of the blame on the bbl. I say that because I got to the point I could pick up (2) cases before loading and tell by the sound of wringing them together if they were the ones that would split. There was a very distinct sound difference. I do realize that even though I contend they were inferior cases, that the tighter chamber did made the difference.
XtremeVel said:Thanks for the link ! I have saw the issue that showed the top round in the pic with the nose end down. Not as common, but I have also seen what the one poster described as a round actually rotating 180 degrees in the mag, thus being in the mag literally backwards ! These instances I saw while playing with the OAL, and haven't seen them since I found that at 1.25 is what mine like. I use either a Dardas 200 gr SWC or Missouri's offering. Now, the tactical feeds them fine, but I will occasionally get the service to FTF every so often. Not like in the pic anymore, but rather the sharp shoulder catches as it enters the feedramp.
XtremeVel said:I understand that you're not saying that. The same as me ever saying that the oversized/unsupported chamber couldn't possibly make the difference of a gun KB'ing when a person does eventually run into that (1) situation of a double/overcharge, case failure, or bullet setback.
XtremeVel said:Do you think this is what many Glock fans do ? I hope thats not the impression I give to others. I do feel there is much truth to the issue, but I simply do not feel it's much to worry about as long as I do my job correctly.
XtremeVelThe one thing I hate is the haters who avoid the Glocks because of a possible KB due to the exact reasons we are talking about. The part I have trouble understanding then is why stop there said:I get your point about polymer frames. Just remember that the chamber has to let go before the grip/frame can be damaged. If the chamber is designed properly then I'm not worried about the plastic shards that could result from a kaboom.
XtremeVel said:Thanks again for the link ! I pretty much just read a few posts so far and looked at the pics. I will read more as time permits and see if I can't figure out how to get the service to run as well as the tactical with that 200 gr bullet.
No problem at all. It is a very long, informative thread. The post about the design changes in the XDm45 cemented the decision that it wouldn't be redundant to purchase that in addition to my tactical.

I'm aware that glock has quietly added some support but I disagree with your conclusion that the chamber design complaint is somehow now a myth. Why doesn't this fact completely validate what we've been complaining about for over twenty years. Glock has a long history of fixing gross design problems as quietly as possible or offering voluntary "upgrades." For glock to make this change there most have been sufficient reason. Glock must have seen enough trouble to warrant adding support to the case.

The difference is less but there is still some difference. The six o'clock case support is only part of the problem. It is difficult to tell by just looking at a picture but can you tell how the case is looser in the factory barrel than the aftermarket one? Glock chambers are not only under supported but they are also oversized. The fact remain that, despite the change, that is still the case. It is a step in the right direction but they need to be wise enough to actually make a properly sized, fully supported chamber. If they fixed that and a few other design flaws they might get some of my money.

Again, case support is only part of the issue. The best part about this is that there is no good reason to not properly size a chamber. There is no noticeable difference in reliability between the two designs.
Edbean said:

You haven't presented any evidence to form this conclusion. Glock confirmed that problem with the chamber redesign and there is still a notable difference in the dimensions of a glock chamber and any one that is considered fully supported.

What does this have to do with the current topic? When have I suggested that a polymer frame will contribute to a kaboom? You are arguing a non issue. Yes, if you pack enough powder in you can blow any gun. Chamber design will determine the threshold required for that to happen. For now that threshold for glocks is such that there is a chance for problems with factory ammunition.
