I love bullpups. But before I shell out a penny I need to know the availability of the chokes and the barrel extention. The Puma K12 did not meet my expectations because it would not cycle trap loads. A barrel extention would have solved that. Please convince me as to why I should give up my 1989, 870 that has never once failed me in over 30 years of abuse? I need a gun that just works. Spare me the bullsht about high brass low brass ,full moon, or who made the shells. My 870 runs everything. Never once in at least 2k rounds of anything and everything has it failed me.
