I have FNP45 with Streamlight TLR2 light/laser combo on mine for home defense. I absolutely love it. definately not best for carry, but for sitting in bedside table drawer its perfect
I would not put a light on my HD gun since you have to point your gun at what you want to light up and if that turns out to be a family member, not good. I would rather control the light with my left hand separate and have an Olight M20 r5 Warrior where everything can be controlled by one hand (no twisting).
IMO your first listed choice is the way to go!
I have one in a 9mm that matches but James Burwell did the trigger/action work.
I was going to suggest an XD until I saw your comment about the grip safety. Since you own a 1911 with a grip safety what is it about the XD's that you find annoying?
