Glock 40 Chamber Support

[TXCOONDOG]

For those of you that have aftermarket barrels, please measure the chamber at the ramp and post the measurements.

List what aftermarket barrel you have too. If memory serves me, it seems that I remember reading somewhere that KKM and/or maybe another manafacture opened up their chambers for more reliable feeding.

KKM will give your barrel a little more room in the throat.... If you request it...

By room in the throat, I mean the area that creates the "Glock smile"... They offer this for better feeding of wide flat nose bullets that aren't crimped much, if at all.

My KKM doesn't have this treatment... Support isn't what I'd call full, but it is far better than the factory barrel.

I'm not home to measure it.
