SIOUX FALLS, S.D. (AP) — Sioux Falls police are exchanging power for accuracy when it comes to the weapons they carry.

Over the next year, the police department in South Dakota's largest city will be going from .40-caliber Glocks to 9 mm pistols. Chief Doug Barthel tells the Argus Leader newspaper that the pistols have better accuracy and the ability to carry two more bullets than the Glocks.

The change goes against a trend in law enforcement in the state. A recent attorney general's study of 61 police departments found that only three use 9 mm pistols — down from 12 in 2001.

The Sioux Falls Police Department hasn't bought new guns for 17 years. Federal grant money is funding the purchase.
