this just arrived an hour ago, havent had much time with it yet. I have occasional shots where the velocity is very low, but the rest hit pretty hard. Im guessing the plunger needs to seat in better. Id also ordered a spare magazine, but the only ones I found do not activate the slide hold open as they're for 1.0. On a surprise note, that little toy sight is somewhat usable. Time to go annoy my wife more as I test break this in.
