I am thinking of getting the shield or the glock 26 or 27. but they are the same size as my xd. i am looking for something even smaller for those days I have less on and its more noticeable... what do you all think is the better gun? shield or the s & w m & p compact 9 or 40... or looking into a kel tec or something in between. even a diamond back? a 9 or 40 but small. maybe the single stack glock 36? but its ABOUT SAME SIZE AS XDS?... WOW SO MANY TO CHOOSE FROM. HELP?
