I own one, bought it last week. Went and ran 150 rounds thru it to see how it works.
The sights are windage adjustable rear and replaceable fronts,they work nice and have a good picture.
It has an ambidextrous magazine release and ambi safety both good features and hard to get on a .22
The fake comp bbl weight is cool and helps balance the nose quite a bit.
Bad news, The grips are perfect for a woman or teenager with smallish hands, to small for adult males. The trigger, horrible double action, moderatly crappy single action. I think the single action will work in a bit but the double will always be HEAVY and long.
BUT, for 250 dollars it is a lot of pistol. I like the looks and it does run really nice. I ran some doubles and it was nice and quick,points well. I got it for my daughter and it will be perfect for her.
