Currently have both. Gas operated models are an old skb 1300 and beretta 390......both very reliable 12s and low recoil. The inertia is benelli monte 12 that is slimmer, just as reliable but with noticeable recoil by comparison.
A used 390 in good shape is a sound investment, every beretta gas gun I ever had shot 1-1/8 oz loads fast and smooth as silk.
