I'm getting ready to take my CHL class and everyone is telling me that I need to use a semi auto handgun for it. All I own is revolvers and I have never gotton on the semi auto band wagon. I know that if I go with my revolver that is all I will be licensed to carry which is fine with me. I'd would like to know if later on I can add the semi to my license if I feel the need or am I forever stuck with the one type?
