I know there is alot of info that I have seen in the FAQ about fitting but was looking for some more advise. Was able to puchase a handi and one of my extra barrels locked rite up with no wobble and descent even latch up and no space or light visable between the barrel and receiver when locked. I tried with a live round and it needs to be shut with a little force but it locks and still has some latch play still with no visable barrel gap. There is a little scratch that develops on the primer. The latch is engaging well straight across evenly. Should I shot it and see how it goes or shoild I be looking at doing some work to it before hitting the range. Really didnt want to modify the barrel.
