I'm wondering if the sites for the regular pistol would also work for 9-M or not. I wouldn't see why unless the front would be too large from the shorter barrel (barely though). IMO, if the 9-M had better sights, it would be the most perfect pistol I've ever fired. Currently, the sights sit too low on the slide, which has a curved top, so it interferes with the sight picture as does the bottom of the rear sight, since the dots are so low on it.
I'd just rather be for sure at $80 that they're actually going to be worthwhile improvement
