My 8 year old 1300 pump gun has never failed to function perfectly.
It will fire just as fast as I can pump it and has never jamed.
I can't say I have seen my other shooting buddys auto loaders work as well.
My compaint is the look or apperance of the stamped steel parts even though the part work as designed they give the gun a cheaper than it cost look.
And the plastic triger guard also looks cheap but it is strong. An machined investment casting should have been used.
I do hate the location of the safety button on the trigger guard it a bit far for my small hand to reach.
