If you have a VP9 in a Muddy River Tactical Kydex holster and you put an optics ready slide with suppressor height sights on it, you are going to need another holster. It fits but won't go all the way in, leaving the trigger guard uncovered.
In a nice coincidence ( for me), your VP9 with suppressor height sights WILL fit in your Muddy River P30L holster. AND it will leave room for your optic.
