The 590 is a
very different gun than the 590-A1. The former is a suped up 500 which is a great gun to begin with. The 590-A1 is a very hefty military gun designed not to dent the barrel on ships' ladders.
In order of my preference...
- 590
- 500 - 8 shot
- 590-A1 6-shot with a Vang Comp Mag Extn.
- 590-A1 9-shot
Been there, done that with all of them. And BEAD SIGHTS -- no silly "GRS." Ghost Ring Sights are for rifle/slug shooting, not a shotgun if you know how to use them IMO.
