Are there any GSSF legal basepads that can be installed on a G29? I seem to remember that in the subcompact category, one aftermarket brand (Pierce?) of basepad was allowed. But I can't find the rules online anymore. The GSSF website has course descriptions, but no longer lists the rules relating to equipment. (or maybe I just couldn't find it). I had thought I could install a basepad from a G30 10rd. mag and make it work, but I was mistaken. The G30 mag tubes must be different length for the 10rd. vs. 9rd. mags. If there is nothing I can add to a G29 mag, has anyone ever tried shooting 10mm through a Glock .45 mag?
