The M9 pistol typically features fixed sights, which include a front blade sight and a rear notch sight. These sights are designed for quick target acquisition and are generally made of metal for durability. Some models may also be equipped with night sights or adjustable sights for improved low-light performance or precision shooting. Additionally, aftermarket options such as red dot sights can be mounted on the M9 with appropriate adapters.
As of 2014 they go for 5-$600. Great pistol. Very natural fit to the hand, great sights.
