NineX19’s precision machined sights for Sig P320 and P365 models are one of the best values on the market and include some very convenient features for the Sig builder and customizer. The blacked out rear sight and Night Fision® tritium front sight provide a clear and repeatable sight picture for accurate shot placement even in low light conditions. The innovative punch holes on either side of the rear sight make it possible to install these sights without the need for an expensive sight pusher and without damaging the sides of the sights.
Dimensions are measured from the top of the slide to centerline of the sight:
Front Blade Height: 0.260″
Rear Blade Height: 0.275″

- Blacked out rear sight with green Night Fision® tritium front sight

I actually had higher hopes for these sights. While the rear sight looks good. Thee front sight when installed, there is a small gap between the bottom of the sight and the slide. I have photos, but there is no way to include pictures to this review. Maybe my expectations were too high. I’m sure I will be changing these out with new ones and these will get thrown in my box with old sights and holsters.
