I have a Legion 226. I also purchased a 18 round Mec Gar mag for it. However, I would like to use the same 18 rounder for my 229 Elite Enhanced. It fits and works perfectly in my 229 but there is a small gap at the base of the magazine that I would like to try and close. I have seen a few sleeves but Im not sure that I'm ordering the right one. I have a X GRip in my Glock 26 that allows me to carry 17 rounds but the sleeve for my Sig is proving to be a bit more difficult to find the right one. Can someone guide me? Thanks!
