I have a 625 Spotlight Grade 4 in 20 gauge. I love it. The fit is just fantastic and a sub 6 pound gun feels better and better as the day goes on.
Obviously they do not offer the recoil reduction of an auto.
Are they worth if? Only you can answer that.
Went 2 for 2 on first roasters I saw while carrying this shotgun. Pretty much sealed the deal.
