P09c FTF but only with a light attached

I’ve had a p09c for about a year now and am coming up on 1000rds. I was a bit worried after hearing the horror stories but i haven’t had a single issue with it until now. It has a holosun 407k mounted but that hasn’t caused any issues.

I recently bought a TLR-1 HL for it and took it out to the range and immediately had a FTF. I couldn’t get through more than 3 rounds without it jamming. I initially thought it was an issue with the gun but without the light mounted it runs flawlessly. No matter how tight the light is, the gun jams., even if the light is barely attached.

is it possible that just the extra weight on the front is enough to keep it from feeding?
