So, I'm getting the burn to get a p365XL. Basically, the main reason would be to get a red dot mounted on it (old eyes). I just found out that the Romeo Zero One requires the optic to be removed for a battery change and that it is constant on. Does anyone know of an optic that can mount to the p365XL that does not require removal for a battery change ? +1 for not always constant on. Or am I overblowing this ?
