Requires exactly one pump to provide enough air for a single, highly consistent shot. These are often found in Olympic-grade target pistols.
While the concept of using compressed air for propulsion dates back centuries (most notably the Girandoni air rifle used by the Lewis and Clark expedition), the "modern" era is defined by the shift toward high-pressure reservoirs and regulated valves. In a contemporary PCP system, air is compressed to pressures often exceeding the modern pneumatic airgun pdf
. This stored energy allows for multiple shots from a single fill, eliminating the "recoil" or "double-kick" associated with spring-powered rifles, which significantly enhances accuracy for the shooter. Key Components of Modern Design The Regulator Requires exactly one pump to provide enough air
