Kyrie,
Photo attached, the barrel weight is stamped as 1370 gms, and they are 27 3/4” or, about 75cm. The original chokes were modified and full, I let them out years ago, as most of the rainy day birds I shoot at are grouse. Total gun weight is 6.6lbs, it gained a bit of weight, .1lb, when it got a new recoil pad. 14 5/16 ths LOP, which, is OK when I have heavier clothes on. In a T-shirt, 14 1/2- 14 3/4” is better.

It truly has never occurred to me to use a 3” round in it.

Truly.

Best,
Ted
