 Nevertheless, even the critics from Gunsite concede that the machine pistol is useful for a few situations, such as boarding an enemy boat in low light or when repelling boarders in a naval situation.In the 1970s, International Association of Police Chiefs weapons researcher David Steele criticized the MAC-10's accuracy when he described the MAC series as "fit only for combat in a phone booth".Walt Rauch notes that "... despite the 50 to 70 years of bad press that has accrued to the concept of shooting a hand-held machine pistol", in which critics contend that the weapon will "spray bullets indiscriminately all over the area", he believes that the 2000s-era models such as the Glock 18 are controllable and accurate in full-auto shooting.
