I had the RP5 pistol in .177 for Christmas.
No prizes for guessing who bought it.

Despite the fact that it was clearly designed by a Committee it works well and I like it.

The mags are different but dont take much getting used to.

The pistol is powerful and has a good shot count.
It handles better than it looks and seems well built.

Havent shot it at the range yet but reviews show accuracy good.

The carbine doesnt have full open sights.
It cant be shot as a pistol - does around 10 ft lbs.
I think it will bring the best out of the pump action, but its not a rapid fire machine just a different way of cocking.
