No problem....it'll shoot the shorter ammo just fine.....but here's the rub...Because the 3 1/2" gun actually is built to the somewhat higher SAAMI pressures of the 3 1/2" shell it might weigh more.
Check out the weight of the gun before buying it.....I'm not sure the Browning website includes the weight of that gun.
BTW.....I have the SKB 505 field in 3" 12 Ga and 26" barrels....it's a very fine alternative and I'm like you.....no need for the 3 1/2" gun. And as a little kicker, it's a few dollars less!
