hmmm.
My P220s fired everything I put in them. .45 ACP.
Any idea about bore size of the p220? I was shooting one last week and the bullets were tumbling. The same rounds were not tumbling with a 1911 and a S&W we were shooting.
The P220 is the only factory firearm I ever had that wasn’t choosy about .38 Super ammo. I can mix Cor-Bon DPX and Power Ball, Silvertips, and cheap ball in the same magazine and it chugs right along.
