The latency on LCDs is much much higher, often as much as several frames. This could be removed but only at the cost of disabling all manufacturer's image post-processing including upscaling.
I have a "100Hz" CRT television that won't support light guns because the manufacturers decided they'd put this kind of image-"improving" technology in.
There are actually two techniques for light gun operation, one of which is "racing the beam" (unreliable in the presence of high retention phosphor) and the other of which is to draw a single frame of white squares for targets. https://en.wikipedia.org/wiki/NES_Zapper#Technical_details
