So... I picked up a 15rd mag from botach because they have had a pretty good sale going on mags and I went ahead and grabbed an xgrip with it as well... For starters... It just feels strange but I would imagine its because Ive gotten so use to how my little lady feels in my hand with out the extra 6 rds. Its certainly heavier feeling. Im curious if anyone else has this set up and has had any range time with it... does it feel terribly different? Do you notice any difference in double taps? Ill probably hit the range with it this weekend if I can muster the courage after my last range incident. FWIW... I also ordered a light holder for the mag plate... I miss my tach light on my G17 and without a rail its the best I could come up with. I figure... when Im carrying it'll be the stock mags with my pinky extensions and when its hanging on my headboard in a mic... she will be packing 15 with my nighttime flashlight attached. We will see how it goes.
