BudsGunShop.com - +P ammo

It absolutely can but, as stated on the RIA website, use sparingly and don't feed it a steady diet of +P. This pressured round will put more stress on the internals.

Hi Timothy and welcome. Yes, but due to accelerated wear and tear, just inspect and maintain your firearms on a more frequent cycle and you will be fine. Cheers, stay safe and enjoy!

yes it can however with P= usage you should replace recoil spring at a shorter interval and they will increase wear of other parts

Hi Tim, yes sir, the RIA Ultra CS will handle +P ammo.
From RIA web site - "Yes all of our guns are +p ammo ready, but please use only when necessary."
Stay safe & have a great day!
