I personally carry a Glock Mod 36 .45 auto here in Florida as a concealed carry weapon. Prior to that in the last 4 years were the Sig P239, Sig P245, HK USPC .40, Glock 26 and finally a Glock 27. For one reason or the other I decided on giving them up after a period of time.
1. Sig P239. Caliber was good, but for the size of the pistol it didn't hold as many rounds as I wanted, and still it was a bit big.
2. Sig P25..I loved that silly thing, but it would drag your pants off when loaded with 6+1 rds of 45. It also had rather brisk recoil.
3. HK USP .40C..compact ..ya gotta be kidding. I know guys who swear they can hide one, but I'm not one of them.
4. G26- I was never comfy with 9mm. Especially with reduced velocity in the 3.5 inch barrel.
5. G27, yep..its nice but hard to control when you don't have a peirce grip extension for your pinkie. Ok..I got one, but now its a larger pistol. Anyone who carries knows that the hardest part to conceal is the pistol butt, not the slide.
so finally I have my G36..I love the .45, recoil and weight is manageable, and the size is comfortable to conceal.
So to make a long story short, I gave all my reasons to point out that only you can make that decision through trial and error and carry something that gives you peace of mind. If a .22 gives that to you- tell the mockers to kiss your uplifted posterior, because you have what you need until something changes your mind.
Good Shooting
