The 2" pretty much shoots 28ga loads through a 12ga bore. The Brit 2" guns are extremely light, but it can be tough to find one with both decent LOP (many were made for women and youngsters) and barrels longer than 26". The new Spanish 2" guns weigh at least half a pound more than the vintage Brit guns, but are all proofed at the current CIP 2 1/2" standard of 850 bars. But ballistically, you still have pretty much a 28ga using a 12ga bore. And there are a lot of 28ga sxs lighter than the Spanish 2" guns. Ammo availability, ease of reloading . . . 28 definitely wins out there. But if the equivalent of a 6# 28ga still trips your trigger, why not.
