Editing Sheridan (section)

=== Development of the PGP ===

The original PG was a bolt-action paintball pistol using a tubular magazine.

Players and aftermarket manufacturers subsequently developed pump-action conversions to simplify loading and recocking.

Sheridan introduced a factory pump-action version, known as the '''PGP''' or Paint Gun Pump.

The PGP incorporated a sliding pump handle and retained the compact construction and internal magazine of the original pistol.

It operated using disposable 12-gram CO₂ cartridges and became a widely recognised marker in stock-class paintball.[1][2]

Sheridan subsequently developed rifle-style markers using related operating mechanisms.

These included the PMI-1 and PMI-2, along with the KP-series rifles and later P68 variants.
