I just picked up an HK45C in a trade. It came with an 8rnd mag and 10rnd elephant foot mag. I like to carry a spare mag, can I get a flat baseplate for the elephant foot mag? It's so bulky and I normally pocket carry my spare mag in a DeSantis Mag Packer. Any issues with fit/functionality doing that, or do I need to just pony up and buy an extra 8rnder?
