If I may add my 2 cents here, I would suggest carrying a bigger weapon because you dont have to worry about sacrificing size for concealment as people who carry concealed do. Use the fact that you are open carrying to your advantage as much as you can. Maybe upgrade to a Glock too lol.
Now there aint nothing wrong with your gun, but in my opinion, if you're gonna carry openly, carry the best gun you have. For me that would be my full size. Depending on dress, if I want to conceal, I sometimes have to use a smaller gun. But carrying openly, Ill carry a full size gun with longer barrel and more rounds in the magazine.
