Aftermarket G19/45 C Barrels ?
I see that Glock made a GenV 45C model. I am going to try and get a Glock into my collection this year and wanted to know if the brain trust here was aware of any aftermarket company that makes a drop in barrel that would have the compensation ports in the same spot as the factory barrel?

I like the idea of a conventionally rifled barrel with better case support so I can use reloaded brass and cast bullets for cheaper plinking.

Thanks HRK but they require fitting and the ports are a bit different than factory. I may be looking for a unicorn on this one.

I've never heard of an aftermarket Glock ported barrel that matches up with the factory slide cuts personally. However the later Glock barrels are well supported if you're laboring under the misapprehension from the Gen 2 days. And you can shoot cast bullets in them.

Best I can think of is the GlockStore does what they call the C cut which recreates the Glock factory C porting in 10 days.

Many guys I shoot with took advantage of this. All were very pleased with service, function and price. It seems Glock Store gets this right.

Thanks guys. If I snag a G45c this fall/winter that may just be the ticket !

The GlockStore might even have premade Gen 6 guns by then.
