I curious about the thickness issue. I thought the 75 would be chunkier than it is, especially since I ditched the thick thumb rest grips. I don`t have a HiPower to compare with. Would it be possible for one of you guys who has both to measure slide and grip thickness and maybe circumference of the HiPower? Pretty please. My 75B with Hogue cocobolo grips measures 1 1/8" thick at it`s widest point(BTW it was at *least* 1/8" wider with stock grips). That`s only 1/16" thicker than my single column polymer Ruger P-97 (the Ruger is actually thicker if you count the Hogue grip sleeve`s palm swells) and 1/8" thicker than my Keltec P-11. The slide measures about 7/8"(actually 29/32"),or roughly 3/16" less than the P-97 and 1/8" less than the Keltec(!). I wouldn`t have believed these measurments myself if I hadn`t just measured it myself with a machinists rule! I`ve never measured a HiPower but if it`s really much slimmer than this I can see why folks like to carry em! Marcus
