A while back I thought that I had the Millet Series 100 P85 rear sight, but the dovetail base on the sight was woefully short, leaving about 3/16" of the slide dovetail slot uncovered. Which means the milled out recess for the firing pin block is exposed to the outside... And the sear block spring is _just_ covered by the base of the sight.

Just picked up what MIGHT be the actual P85 rear sight, it has a much wider dovetail with a allen lock screw on either side of the rear sight blade... What I might actually have installed was a rear sight for the Mark I or so .22 LR pistol, which is a much different beast.... The Mark I rear sight lacks any allen lock screw, and for a .22 LR, you probably don't need it.

Pictures when it arrives...

The mighty Casey has struck out. The dovetail base on the sight is the same >short< width as the first sight. With only two Series 100 sights, I'm not positive, but it MAY be possible that the Millett Series 100 was designed for the P85, not the P85 MK II. The original P85 slide did not have the cut for the firing pin blocking spring, and the short width worked. Go to the MK2 with the milled pocket for the blocker, and the blocking spring wants to pop up if the Millett sight is not mostly covering the pocket.... I can find no way for the Millett sight to >completely< cover the firing pin blocking spring hole... :cry:
