My wife is deadly with her Sig 320RX 9mm red dot but saw, and fired, a Urban Grey Shadow 2 and fell in love with the weight and trigger! Santa was good to her as she got one for Christmas! We went to the range today and I put the firearm in a Hyskore pistol rest and it fires to the left at 10 yards, where she usually shoots. The manual states that the firearm was factory fired at 25m. I read many horror storys regarding moving the rear sights such as heating the sights, using a hammer and really slamming the sight dovetail, using a sight pusher, etc. By the way what is the best sight pusher as most get poor reviews. Has anyone had success moving the sight without scratching the firearm and beating it to death? Also, can a red dot be installed on a CZ and has anyone installed one? I usually never purchase a firearm with non adjustable sights but my wife loved the firearm. Or is my best bet to send it out to CZ Customs or another CZ firearm repair such as Cajun Customs?
