TRUGLO 2X
I recently purchased one for my Ruger Mk 2 target pistol. I hade been using the pistol for action style matches (timed plates, etc.). At the longer distances, I was having trouble hitting the target. So, I tried out the 2x truglo. It is just as ss7 says - the dot jumps around too much at long distance to get a quick and accurate shot off. That said, it might work better on a rifle or long barreled hunting pistol. Regarding quality, it's pretty cheap. The detents for the dials are very mushey. Good luck.
