Is this barrel rater to handle +p ammunition?

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

Yes, the SIG SAUER P320 9 mm Luger Barrel will function with factory loaded +P ammunition. Only use +P in light amounts as extended use can cause accelerated wear to the barrel.

Q
Nick, member, from MA, United States, asked on January 30, 2021

Will this work on the M -18 model?

Expert Answer
A
Answered by Armando R., Gear Expert, from IL, United States, on February 23, 2022

The most current offerings from Sig Sauer under these part numbers will have the loaded chamber indicator so they should be compatible with the M18 as long as you get the compact or full size barrel as the sub-compact barrel will be too short.

Can you tell me if this has the loaded chamber indicator? I need one without it.

Expert Answer

Answered by Armando R., Gear Expert, from IL, United States, on February 23, 2022

The most recent offerings from Sig Sauer under these part numbers do have the Loaded Chamber Indicator cut out which means it will NOT work for your application if you need one without the cut out.
