Hey Guys! So I'm trying to decide on my next firearm purchase between a G26/27 or G19/23. I currently carry a G43 and love it, but am looking for something to serve as a good home defense and occasional CCW. My concerns with the 19/23 are that I live in Florida where it's always HOT and I'm a small guy (5'8" - 130lbs), so I tend to run into some challenges with concealing a larger gun. I used to have a G19 and enjoyed shooting it (should've never gottten rid of it). My father carries the 45acp baby glock as his off duty weapon and loves it. One of my thoughts is getting the 26/27, and then getting mag extensions for when it's being used for home defense... Another thing is .40SW or 9mm. I currently only have 9mm pistols, and feel that it would be nice to diversify my calibers. I've heard both sides of this from people saying it's better to standardize your caliber and others say it's better to diversify it. I personally think it may be better to have more than one caliber (i.e. ammo shortage in one). What are your thoughts? What should I get? Thanks!
