I have had a concealed carry permit for 34 years, and I shoot a minimum of 100 rounds/week in practice. We are fortunate here in Huntsville, Alabama, to have a fine in-door range at Larry's Pistol & Pawn, so there are no excuses for not practicing often.
I also shoot in a local IDPA match (also at Larry's) approximately twice a month.
