I have my 9mm bases covered, 19 and 17. I have old school 1911 but no modern 45. Would you get a 21 or a new caliber, say a 23 (40)? I carry a 22 at work but I never liked the recoil. Maybe a 23 witth some undercutting (demel) of the trigger guard would stop the Glock knuckle I get with the 40. Does the 26 play a role with the others?What to buy now?
