These pistols are powerful target weapons. They come in three calibers and depending upon model, have different features to make them unusual. The standard Practical VB has a scope mount that may mount optics ranging from laser aiming modules to telescopic sights. The Practical VB Elite is the best target model, with a compensated barrel, micrometer rear sight, and the controls are enlarged for easy manipulation. The Target version is the simplest version, designed for the strictest competitions; it is almost like the Elite, but has no compensator. These weapons were introduced in 1992.
