The Crimson Trace Rail Master is an awesome sight, compact, powerful see the green lazer out past 100 yds. Nice is that this sight will fit any semi auto with a rail. Compact lets you use existing holster nice not to have to go out and purchase a modified holster to fit the lazer. I did a ton of reaserch this was my choice.....the green lazer can be seen the brightest in all light conditions,
Good Shoot'n
