I haven't tried this one either as it just came in today. It works by hand but that short barrel may make it picky. might need some buffer changes. i have an H3 in it now.
I have a 22 Vector, while it does work decently. i did have a couple jams but nothing serious but after owning it i decided i wouldn't have any other one in any caliber. awkward and very user unfriendly. or it is to me.
