Now that I'm a 1911 expert... ....I have a question about the CM mags I bought. The baseplate for all of my other pistol mags is removable but looking at the construction of the CM mags I don't see how they can be opened up for cleaning. My main concern for cleaning the mags is that I shoot competitions and the mags end up being dropped in this FL. sand and it's nice to be able to disassemble them for cleaning. So how does one clean the inside of these mags?
