Q:  What Sights come standard with the P7?

A:  Standard 3 Dot Sights (Exception P7K3 USA Pistols)

All P7s come standard with 3 Dot sights.  The original P7 sights were installed in the dovetail in the slides and secured with a large screw in the rear sight. 
Early P7 M8 models also included a tiny pin to secure the front site in addition.  The P7 rear sights are shorter than the P7M8, M13, M10 and K3 sights. 

These K3 sights have the front pin to secure them
 

 

P7 K3 USA Import Pistols had plastic "Target" sights on them
to meet the import restriction "points" goal
