Hi Guys, New to the forum here but just picked up a 590a1 (model 53693) so I think that qualifies me to hang out with you all So, I'm deep in to the accessory rail items hunt (my wife says picatinny is like Barbie for men) and I am also looking for the best selection for a bayonet. I know Mossberg sends the Ontario M9 with the SPX model as stock, so one would guess that would be a no-brainer...however, I have read bad stories of them occasionally being too long in the handle and having poor fit or falling off while firing. Similiar stories with the OKC3 USMC version of the Ontario bayonet as well as the ZT-9 (Strider/ZT colaboration)are out there. I can't imagine that there is that much of a tolerance issue where it's a hit or miss thing but the information I have seen is certainly conflicting. What are your experiences with bayonets and the best one for the application?
