You have the same setup. I remember seeing your video when I was looking into the dot and mount. I really don't mind the height much. I need to measure my 22/45 with 90 c-more and compare the two. I would want them close as I can because I shoot local steel challenge weekly also. I used the 19 and 18 round magazines with no problems. I don't know if I will even mess with the 140 mag bases
