my gen.4 19 has a slight bevel on top of the barrel in front of block where it meets port in frame. why? is this normal as this is the only Glock I have this way.

Nope mine is square as well... Different viewing angles available?

 

[sgtcowboyusmc]

All of mine are square or nearly so. Both of my 30's seem to have a slight angle but not like yours. and my 21's All are straight up and down as is my 1987 G17. Could you take a pic with the slide locked back?

Mine is the same

sorry about poor pics maybe this is a little better. BTW it shoots great!

WOW that is quite a bit! This new for the Gen 4's? I don't have any gen 4s. Different I will say!

 

[sawfiler]

yeah I was wondering if it's a Gen 4 thing. I have a Gen 4 21 and it's straight?

 

[RockoutwithmyGlockout]

My Gen 4 17 isn't like that... Neither is my 27... Hmmm....

 

[SeventiesWreckers]

Kinda Dusty, but my G21 Gen4 has a beveled top. Never thought about it.

Are you talking about the barrel hood or the slide?? Not sure where you are refering.

[sawfiler]

yes barrel hood is beveled I'm not talking about the wear mark some call "Glock birth mark" it is actually beveled. I think I misspoke when I called it the monoblock.

 

[dwcfastrice]

the bevelling is there to help the slide "climb over" the barrel.

D

 

[sawfiler]

now that we know other Glocks are this way and I can actully see how it might help it even I guess what I'm wondering now is why some have it and some don't. is it determined by someone doing final fit at factory or what? just curious as I said my 19 runs great no problems.

Afaik, the gen 3s came out squared and then later on had the bevel.
My gen 3 is beveled, I have seen them both ways, I just wonder why this isn't just the normal process as they seem to keep returning to it.

Don't hold me to this...but I think the history behind the barrel update to the G19 has to do with Glock addressing the issue the NYPD had with phase 3 malfunctions. I don't know exactly when it was implemented, but the older Gen 3's that had the update had a "1" added to the SN# on the barrel (see pic). Now my other assumption is ...after a while, Glock stopped adding the "1" to the barrel SN# since it became standard. That assumption is based off the fact that my relatively recent Gen 3 19C does not have a "1" on the barrel and neither do my Gen 4's.

...that's all I got, someone with more knowledge will correct me if I'm wrong.

great info Kodiak! maybe I'm the only one who doesn't know but what's a phase 3 malfunction? and thanks!

Not the only one, I'm not familiar with it either, I'm guessing it's a failure to fully go into battery.

Here is a little background with NYPD that explains it. The article appears to be written before the final fix from Glock was known:

Here is a thread that explains what Glock did...Note: Barrel bevel
