Knowing house clearing is controled accurate fire that pretty well puts the mac 11 at the bottom of my list of want toown firearms. Other than for mall nija range fun day is not very practical for much of anything. Does any one really thing a glock is not reliable? Guys can buy glocks and go directly to matchs and be competitve. Don't think a mac 11 can do that ,so its an easy choice here. Semiauto Glock 19 makes for a good CC handgun glock 17 a good duty pistol They can both use the 33 round mag if that floats your boat too. And for the machine pistol guy you have g18 with select fire.. Any glock would be my choice. And I am not a glock guy at all.
