Whether you are an introductory air gun shooter or a well seasoned professional, Walther's LP500 Expert pre-charged pneumatic air pistol has all the tools to make you a better shooter. It uses a refillable compressed air cylinder to fire .177 caliber pellets into incredibly tight groups. The match grade barrel is 8.7" long and is ported to give the shooter better control of the gun as its firing. With an ultra-light pull weight of just 1.1 lbs, the two-stage trigger was designed to be as precise as an air pistol trigger can be.
