i had a similar line of thinking - i have the Galloway Precision +1 extension - makes my 6 a 7 - i don't see why one couldn't buy the 7 round MagGuts components and using it with that to obtain 8 rounds in the magazine - why would it be any different from having a 7 round Kahr magazine and using the +1 MagGuts to make it 8 plus one chambered? Or, just use it with one of my 7 round Kahr mags - still like oldtimer said, $29 bucks is quite a bit for one additional round
**won't work on the 7 round mags because of the gap - sigh - turning the 6 into a 7 with the base extension then buying the 7 round MagGuts might still work though
i wonder if Kahr will ever sell a cuff to close off that gap in longer magazines - i have one with my FNS 9c and it makes a helluva difference
