Welcome to the forum! I think its great to see new gun owners!
I'm curious to know why you would want to carry a .22 lr. Are you looking to OC as a "statement" or for self defense?
.22 IMO, is not a viable self defense round. Personally I wouldn't carry anything less than a 9 minimeter. I currently OC a Glock 30 which is a .45 ACP.
Best advice I have for you, since I don't know the laws in Independence personally because I never go there anymore, is to check the local code for yourself or ask a competent attorney.
Secondly, pick yourself up a bigger caliber weapon for self defense. The P-22 is great for range plinking, but I would never trust my life to it.
Please don't take my post as an insult, as its great that you want to OC, but I'm sure a lot of people will agree with my opinion of the .22 for self defense.
