While most agencies have switched to a semi-automatic pistol to get more ammunition capacity before a reload, other agencies feel the revolver holds enough ammunition. In any case, the ammunition capacity can be compensated for by carrying a backup weapon or adopting speedloaders. Officers also need to be trained to reload from behind full cover. Despite the perception that police are facing better-armed adversaries, this author maintains that the real problem is the increase in the number of people with guns. Adopting a semi-automatic weapon does not increase shooting accuracy as much as better training will. Reasons cited for keeping the revolver are that it is easier to maintain, simpler to use under stress, fast enough to reload, holds enough ammunition, and is less likely to accidentally discharge.
