Aftermarket Glock 17 replacement barrels etc..

[CanFire]

Thanks for taking the time to post those pics FN.

I was suprised by the photo. There really doesn't appear any difference between the LWD and the Glock 9mm factory barrel in terms of chamber support. For the record, all of the concern about Glocks having unsupported chambers seems to be in calibers higher than 9mm though so I wonder if any 9mm aftermarket barrels would offer more chamber support? I'm sure there is a difference in the .40 and 10mm calibers though.

I (and thousands of others) reload Glock fired 9mm brass. I've never loaded to maximum pressure, but at normal levels you can't see a bulge (minus the normal expansion you get from a non-match chamber). You should be able to reuse your brass 5-6 times too.

The picture is just to keep the glock haters from thinking their "fully" supported chambers are imune to case ruptures - they're not.

I'm looking at my Glock 34 Barrel and My Sig 226 40cal Barrel. Looking at both offers the same amount of supporting around the 6 O Clock. Less then a MM is not supported.

Chamber issue in a Glock 9mm is NIL.......Never a KB, I run a Glock 9mm and never worry about the unsupported chamber because I check my brass and there is no bulges on the case. Also I believe there was never was a report of a KB caused by a un supported chamber with a 9mm Glock.

If a M&P will last 100K-200K like there been reports of Glocks pushing that many rounds out before dying. But nobody put that many rounds though one yet. So better chamber has nothing to do with it.

This thread is NOT about whether or not M&P will last 100-200K (btw just because there are some glocks that made it that far doesn't mean that every one will last that long; maintenance, ammo power lever etc play a huge role) chamber support has everthing to do with this thread;

I am a bit unsure of shooting someone else's reloads in an unsupported chamber especially when I don't know how particular they are with their brass, powder loads etc

This is M&P40 barrel, 9mm is just like that (it doesn't really get better than that with semiautos). While not KB proof it gives you more room for error/margin of safety than a chamber that isn't as supported. Thats all I've been trying to say...

I hate to say, Looking at my Glock 34 barrel and looking at apparently a M&P barrel, 9mm cases fit that close in it on my Glock. Also I'm not worried.

Wanted to bring up an interesting observation I made
when I started reloading 9mm.

Note*
I use a Dillon chamber check gage on every round I make, just 'cus.

Since there has been disscison about Glocks and their apparent
buldge, other brands have it too, even worse. . .
I shoot a Sig 220 in 9mm and a G17.
For fun I wanted to put a 'fired' brass from each gun into my
chamber gage and see how much they have expanded/stretched/bulged.
I droped the Sig brass in there and it stuck out from flush maybe an 1/8"
or so, Ok. I droped the Glock brass in there and, it stunk rite to the bottom!
Flush with the gage. According to this gage, the Glock brass is within
9mm chamber spec, AFTER being fired. The Sig isn't. Mmmmm
I can 'visually see' the bulge more pronounced on the Sig brass as opposed
to the Glocks.
I resize everything anyway of course, but kinda interesting.

I have always been of the opinion that it's not the chamber on Glocks that causes the (Extremely Rare) Kboom, it's the rifling which is not compatible with lead bullets, and guns that aren't properly cleaned. As far as brass life goes, that's more charge dependant than chamber dependant.

 

[CanuckShooter]

maybe you are right Canfire, the chamber support might be the same for the Glock and LWD barrels only in 9mm. You can see in the pic below that on the 40 cal there is quiet a difference in the suppport.

Wierd...

$9 /50 for someone's reload doesn't sound that great a deal... Isn't Centaur available at most gunshow for $10 a box?

The only reason I got an aftermarket barrel for the G17 was to shoot lead... I don't worry about KB in a 9mm, and I don't worry much about case life either, once fired 9mm is plentyfull (and often free).

This is M&P40 barrel, 9mm is just like that (it doesn't really get better than that with semiautos).

The M&P's definately have a nicely supported chamber. The picture I posted showing the "fully" supported chamber was from a 1911 in .38 Super - pretty sad in comparison.

I have been led to believe a Barstow barrel works quite well in Glock pistols.
