Crisp and easy to see sight picture
A very nice quality made sight. Very slight fitting required which is better than being too loose.
The only reason I am giving it 4 out of five stars is there was a "sliver" of steel that rolled over on the top edge of the T-slot when assembling the sight to the slide. This is the second Walter rear sight I put on and had the same issue. I suspect it is due to the odd t-slot rather than dovetail design on the Walther slides that cause this. I would recommend breaking those two edges before attempting to assemble.
