While Crosman has improved the design, this 1377C/PC77 air gun is a throwback to the 1998 model. It features some new modifications to help it catch up with modern technology. As a single-shot gun, theres no way to fit another pellet in the chamber.
The gun operates via a bolt-action pneumatic pump system. The bolt opens only to slide the pellet into the chamber. The actual cocking is done by pumping the pneumatic system.
You need at least three pumps to fire the pellet successfully. Maximum velocity is achieved by pumping this gun 10 times. Depending on your strength, it can fire the projectile at 600 FPS.
The rear sight can be adjusted for wind and elevation and used in tandem with the front blade. By attaching a scope mount, you can even slap a red dot or pistol scope on this pistol. The mount is sold separately.
For target shooting, this air gun will work just fine. Younger shooters can pump fewer times and still achieve excellent results.
Remember that this gun is only capable of shooting .177 caliber pellets. BBs may cause malfunctions.
