I switched from a pump to a Benneli Super Vinci 2 years ago. What a difference! This year I also sprang for a new A400 in 28g. I love both. The 28g has a tighter pattern and you can shoot it all day. The 12g (For me) has the power for in flight geese that I am not sure the A400 could come close to. Having said all of this, I am not familiar with the OU SGs,…
The most fun you will have is shopping,…and then patterning the new SG!
I would stick to the upper end brands though from experience. Benneli and Berreta have always been good to me.
