G20 Barrel.
 

Does any body offer an after market barrel with chamber dimensions close to those of the stock Glock?
Thanks,

BR

Not really. Everybody offers a tighter chamber.
If you want a large chamber (I dont know why?), you can simply ream it out. LWD offers this service for $25

$25! Jr that,s good to hear. I'm gettin' tired of bangin' the slide with the palm of my hand trying to get lead bullet loads to chamber.
Glock reams their chambers a little large so everything will chamber. I think that's what a defensive weapon is all about.
Thanks for your response...I really appreciate it.

We have a few reloaders that do not want to change their loads. this will cause an issue with the chamber. We offer the chamber reaming to off set the problems but really, we encourage reloaders to bring their ammunition into spec.

Well JR, Is there a Saami standard? Would you say your chamber is a minimum Sammi and that Glock's is the max? Is there an in between?
Is there a happy medium between the factory and the LWD chambers?
I appreciate the time you've given me.
