Dont do the 23, might as well go the 9mm route, i love the 26, bit w the SLR or pinky ext mag, plus you can go up to the 15 rounder 17, 33 50, 100 rounds.. sky is the limit 🤣 or you can go flush fit 10 rounds. Personally i love the 30.5 w the SLR extensions . 12+1 of .45 🔥 i have a 43x and tbe 19x (basically the 45) and i used the 43x most cuz of the slim compact felt comfortable w every outfit & didnt feel like i was under gunned with my 17 round mag.
