Hi Daniel, the PC Carbine is able to take American mags if you purchase and install the American Magazine Well from Ruger. Hope that helps you, sir. Remember to select one or more best answers!

Daniel, no. Includes two magazine wells for use with common Ruger® and Glock® magazines. Ships with SR-Series Pistol and Security-9® magazine well installed, and an additional magazine well accepting Glock® magazines is included (older Glock mags WILL work)
