I just bought a Browning A5 stalker 3-1/2" chamber 28" at wholesale last week. 10% off it was $1,600.00. Liking it so far.
The 3" is a couple hundred less. I will never shoot 3-1/2" but it is important for 3gun. The auto load feature is also nice for 3gun.
Only a couple hundred rounds but it is working well. Right now it will not cycle 2-3/4" 1-1/8 oz 1140 FPS shells but it will cycle the same at 1200 perfectly. May change once broken in. Win AA super sport sporting clays (1300 FPS) work great
Good luck
