I have a 590 Retrograde that is an 18” cylinder bore barrel. I’ve been using it in a few tactical competitions and I’d like the ability to tighten up my patterns as the spread from the cylinder bore is a bit too much at distance. This is a 590, not the 590A1 heavy barrel, so I’m wondering if these barrels are thick enough to thread for chokes? Also any recommendations on who to send it to would be appreciated
Thanks
