Research is conducted by the Law Enforcement Standards Laboratory (LESL). Research into the interaction between the firing pin and the ammunition primer will measure the adequacy of firing mechanisms and standards for .38- and .357-caliber revolvers. LESL also is classifying the applications and characteristics of a variety of handgun holsters and is preparing a report on a method to determine handgun accuracy that uses a collimated light source to establish a reference line between the sights and the aim point on a target. A second edition of 'Police Handgun Ammunitions, Incapacitation Effects' will be published in the summer of 1989. Another project will quantify the threat from sharp instrument penetration to body armor, establish performance requirements, and develop a suitable test method. A soon-to-be-published report will help police departments compare the performance of mobile communication systems in the four authorized frequency bands and project the adequacy of existing systems. Performance standards also are under development for miniature surveillance recorders, body-worn FM transmitters, hands-free communication systems, and pen registers. Additional projects will evaluate microwave field strength levels in vehicles resulting from communications transmitters and performance of trunking communication systems.
