A few years ago i personally handled an SO10 20 gauge pair Beretta was shopping around at an NRA convention. At $65K per Gun or $115K/set, I did not see the value.
The small frame A-10 presented a great value to me and i ordered a 20/28 set. I had been looking for a 28 gauge Target gun and had even requested Kolar to consider making one for me but no luck.
I think I will be happy with the A-10, whatever design the locks are!-Dick
