This is a topic I’m not an SME on and not the most educated on. My information is old and not up to date and there are much better online resources than what I can tell you.
Just in general, I don’t think there’s much difference between brands but I favored TM and WE.
Most common popular handguns have analogs or clone versions.
Usually there are subtle fit differences for holsters, etc.
They’re usually a lot lighter than the real counterparts and the recoil isn’t particularly useful for an experienced shooter. Can be good for training newer shooters.
So I don’t think that useful for advanced shooters except for FOF or something similar.
