I imported a few Sheridan F's and Benjamin 3120s in the early '80s. In next to no time the F's were coming back with spent Powerlets stuck to their valve seal! 3120's were returned because the ammo tube rattled loudly!! About this time I decided luckier chaps could do the importing of exotic airguns! Even though the Sheridan E pistol suffered the same problems as the F-it was a bargain at $35!
