If you want to talk about smooth actions,, find a High Standard pump.. with empty gun, cycle action, hold with muzzle pointing strait up, push button that allows you to cycle action again, and without touching forearm, the action will cycle.. In the 60's when military was looking for a new shotgun, they set out to test all the U.S. manufactured ones by shooting 10,000 23/4 magnum loads through them... The High Standard was the only one to complete this test,, ALL the others failed long before reaching this goal..In the end the High Standard wasn't selected, because it didn;'t have a quick change barrell, which they thought might present problems in the field in case the bbl got bent or damaged, it would have to be sent back to an armorer.. but this semi-fixed bbl makes it one of the most accurate smooth bores to fire slugs with, it would be very accurate with a modern rifled bbl. there used to be mag extensions, pistol grips etc. made for these, but not anymore,, they can be picked up reasonably cheap,, a lot of police trade ins out there... a great gun for the price, just no modern accessories made for it now, very smoothe and reliable...Ever seen the 10A or B bullpup auto's that they made,, the A had integral flashlite made into an ar-15 style carry handle,,,, way ahead of their time...
