I had one (20ga Compact model). Although it threw a great pattern (with a Sumtoy .662 & Fed. TSS 9's), the issue was that no matter how much I tightened the magazine tube cap, I could still twist the barrel back and forth a bit (shifting the front sight). I also observed this on a new display gun. Sample of two? My older 12ga Super Nova I had back in the day never did that. That's my experience.
