The OpticsPlanet Exclusive Viridian Weapon Technologies HS1 Laser Hand Stop takes up two M-LOK slots. So if the Ruger PC Charger has two available M-LOK slots this will work.
Yes! I can confirm it does fit a Ruger PC charger 9mm. It does sick out past the front but in going to shave the center tab off to slide it back.
The pc 9mm charger has 1 and a half m-lok slots on the bottom due to the takedown lever. We need to know the measurements between the screws on the laser. There is only 2-¼" of slot available. I would like to formally punch everyone who answers this fitment question with "if it has 2 slots it will fit" or "It's 3.3" long and 1.25" height" thanks for not answering the question. I will update after I order and try it myself.
