I's thinking it was the electroless nickel...wasn't sure, but seemed to look a lot like my 80's Colt and I figure they're not going to make stainless at Handi prices. I've got two other "modern" Handi's I can put some high pressure barrels on. I kinda like this one the way it is. Oh, it has the lightweight barrel with a front sight. It came with a 4x Weaver that, from appearances, has seen two wars.....Spanish American and WWI...well, maybe not that old...on second thought, may have been used as an agricultural implement during those two wars....That, I will replace.
