Q
DirtDiggler2823, member, from MD, United States, asked on December 22, 2022

Does this barrel have the improved feed cone? Will it cycle hollow point rounds?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on January 04, 2023

The FM Products Ultra Light .45 Barrel has feed ramps that have been machined for use with Glock magazines. The only ammunition Foxtrot Mike does not recommend using is aluminum case ammo. Hollow pints will feed and function as intended.

Is this barrel rated for +P rounds?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on March 03, 2023

The FM Products Ultra Light .45 Barrel is compatible with +P ammunition in light amounts. High volume usage of +P ammunition will cause excessive wear to the barrel.
