They haven't been in stock yet, still busy filling the pre-orders. The SSK50 is pretty much a clone of the original easy open Contender and as such you do have to open to re-cock. My SSK50 is pretty picky on barrel fit, I haven't tried all my barrels yet but I have one MGM barrel that won't even start to close, a 12" Hunter barrel that closes and locks like a bank vault but then won't open and a couple that work beautifully. I have yet to get to the range with mine but I think I'm really going to like it and I'm glad to see the replacement parts available once again.
