I have a kimber ultra carry 2 which i can not get to cycle by hand with hollow points. In doing some searching i have seen that i should replace the factory mag with a wilson or a chip mcormick. I have tried emailing mcormick but they must be pretty busy and havent heard back from them yet. My question is what mag do i need to order?? Can i assume any officers type mag will work in this gun?? Thanks in advance for any help. And i dont have a problem with going wison if it is a better mag but for the price i can almost get two mcormicks.
