“The Warwick Police Department issues every officer a SIG P229 – a semi-automatic pistol distributed Sig Sauer,” warwickonline.com reports. “However, an officer may use a weapon of his own choosing as long as it is in .40 calibers. Some officers choose to carry Glocks. Previously, officers could carry anything they wanted but when it came time for Mathiesen to order the ammo, it could get confusing. ‘I had to literally figure out what you carry if you carried a .9 mm or if you carried a .40 mm,’ [Inspector Chris ] Mathiesen said. ‘I had to balance all the info and it was a nightmare.'” Not to mention the nightmare of loading all those rounds and sweeping up afterwards.
