They have a "more supported" chamber. Not that it matters.

Thanks reaper for that pic,its just what I was looking for. Also should I worried about having a kaboom in a Glock 27? This is what I'm wanting as a carry gun and I've read a lot of stuff about kabooms in Glock .40's.

However it seems that it almost always involves reloaded or cheap factory ammo. Is a kaboom something I should even be concerned about? I don't reload or shoot reloaded or lead bullets,I'd only be using quality jacketed factory ammo in the Glock 27 when I get one,thanks.

I am assuming that the gen 4 barrel will fit a gen 1,2 or 3 slide with no problems. Wonder if it would make any difference. My g27 hasn't gone boom yet. But, I can only assume that Glock thought it was a good idea to add more support for the casing for some reason. Does this mean that they realize there might have been a problem? I wonder...:scrutiny:

Nice pic reaper.

My 23C factory barrel has slightly more support than yours (pretty close to the aftermarket barrel pic).

If the OP is concerned on any Glock he owns or is considering purchasing, it doesn't take but about 30 seconds to pull the barrel out and examine the case/barrel fit.

Well my Glock 40s must be defective then. They are well beyond 1000 rounds.:what:

Just try to imagine how many Glock 40s have been produced and sold, and how many kabooms you have heard about. People are going to do stupid things, factory ammo and reloads aren't perfect, and crap happens. Everything else you read on the internet is true though.

Of course not. The .40 Glock is the most popular pistol in the country. It is used by 7,500+ U.S. PD's and many more in Canada, Australia and other lesser nations. It is also a top commercial seller and the king of its class in the various gun games. They would not be the most popular .40 pistol on the planet if this was a real problem. Stop listening to internet idiots who have most likely never even held a Glock.

Nothing has been done to the GEN4 chamber. The increase in support was done 10~ years ago.

As of 2007 Glock sold 5 Million pistols. Most being 9x19mm and .40.

There is no such thing as a "fully supported chamber" unless you're shooting a revolver or single-shot pistol.

With a Glock,

1.) Don't shoot lead bullets in the stock barrel.
2.) Don't shoot reloaded ammunition in the stock barrel, whether is was reloaded by you, a commercial enterprise, or anyone else
3.) Buy an aftermarket barrel with conventional land-and-groove rifling if you want to shoot non-jacketed lead bullets

...and you should have no problems. If you don't reload your own ammo and don't buy reloaded ammo from shady guys at the local gun show, then you will have no problems with your Glock.

I would recommend the following:

- Do shoot YOUR reloads as long as they are loaded to current published load data for your specific bullet type and components are in good serviceable condition (I use mid to high range load data). Toss any questionable components.

- Do shoot YOUR lead reloads but inspect the chamber/barrel every 200-300 rounds or so for lead fouling build up and clean as necessary.

- If you do a lot of shooting with lead reloads, consider an after market barrel with conventional land/groove rifling, tighter chamber and better case base support at ramp area.

- If you reload your rounds near max load data+ and get bulged cases, lower your powder charge. If you won't, I strongly recommend an after market barrel so the brass don't get over-worked too much.

Be safe but have a lot of fun with your Glocks.

Glock does suggest you not shoot lead bullets in stock barrels because their rifling tends to build up lead fairly quickly. This has been demonstrated in tests of their barrels.

I would have to disagree about not shooting your own non-lead reloads out of a GLOCK however. Stock service pistol division of IDPA would not exist if we could not shoot reloads out of our GLOCK pistols. Everyone shoots reloads out of their GLOCKs, and if you know what you are doing, you will have no problems.

The cheapest alternative to lead in GLOCKS is Berry's plated bullets or Ranier Plated bullets. They are ALMOST as cheap as lead, and don't leave lead deposits in your bore, or on you while you handle them.
