Sorry, but i dont understand all the restrictions about red dots for my new Taurus TX 22 Compact, so I am looking for advice on one to get. Believe its the newest version, just purchased last week. Dont wish to spend a lot, but cant seem to find a fiber optic front site for it (has a nut on bottom; not an allen screw to remove front site). Any suggestions would be very appreciated. Just a simple one, please, nothing too fancy or expensive. Thanks so much (wish I knew more).
