Yes, I had one for a couple of years... hated it... didn't feed for crap, shot only the expensive stuff and got gummed up quickly... no warranty to speak us so if it goes south it's not worth it to get it sent to SIG. It's a good looking gun but I would stay away. Our G22 shoots great, no problems. I've heard good things about the S&W 22 although it might be make by Walther? Not sure... anyway, say no to the Mosquito!Anyone have any bad experiences? Are they worth a ****? Do all of them come threaded like the p-22? Thanks
