Hardly ever. My carry gun was last cleaned about 3 months ago and has had about 500 rounds through it since. Modern guns like M&Ps, Glocks, HKs, Walters ...e t c...etc don't have to be cleaned often. This is a whole thing that's left over from the days of black powder and a little later ..finicky guns during the infancy of modern handguns.
Today's guns are usually not finicky, will shoot just about every type of bullet and powder combo and powders are no longer corrosive
