After more than 15 years, the Topeka Police Department is hanging up its 9-millimeter Smith and Wesson hand guns and taking aim with the Glock 40-caliber semi-automatic. "It's a much simpler weapon to handle, simple to take apart, clean,” said Maj. Randy Mills, Topeka Police. “And from the test group we had, the officers all shot the weapon really well." Mills said while the 9-millimeter is reliable, it is a complicated gun. Law enforcement officials said the safety switch on the Smith and Wesson sometimes flips on by accident, leaving officers with less time to react in a life threatening situation. “We're always on the reactive side. We have to react to anything that's going on. We do not have time to think about what we're going to do, so we have to be able to program ourselves to react properly,” said Sgt. David Thomas, Topeka Police. But a change in weapons means officers need reprogramming, which is why the Topeka Police Department will spend the next three months drilling officers and making sure if the time comes, they are right on target. "We’re going to get in repetitions, high repetitions of simple skills, because we have to have those because of our reactive nature,” Thomas said. But the weapons change is not a shot in the dark. Mills said the department talked to other police departments around the state and the nation to find out what gun is being used. He said the Glock has a strong hold with law enforcement and for a good reason. "All the major agencies in Kansas are carrying the Glocks and the L.A.P.D. has them and has carried them for a long time,” Mills said. The price tag to switch weapons will run the police department about $70,000 but Mills said in the long run, the Glocks are more cost efficient. They cost about $200 less than the 9-millimeter.
