I have my new replacement Caracal F and it shoots quite nicely, but the machining is definitely not as precise as my first Caracal was. You can tell they were doing these in a hurry to get them back to the States. Well anyway, I've come across some old Egyptian submachine ammo and I've been itching to shoot it out of my Caracal. But first, before I shoot it, I'm wondering if anyone has shot +P+ or submachine out of their Caracal...I know sometimes it can get iffy with polymer frame pistols. My husband keeps saying I'm going to blow my pistol up if I shoot it out of it , so I'd like to get some input from you all before I do anything.
