Having shot a Sig 226 & 229 consistently for 3.5 yrs, I switched to LEM, and the transition wasn’t a big deal. I assume anyone who has spent ample time with a TDA, could do the same. (If I can do it, anyone can)
It’s easy for me to see how a new/inexperienced shooter might struggle with an LEM, due to the extended travel on each pull. I could see them thinking “why is there so much travel”...not understanding what the system was designed for.
It kills me to see people on other forums (even the HK forum) buy an LEM gun, having shot SF guns, and complaining about how it’s different than their VP9/G19 etc., asking about spring kits and reset kits to make it more like the SF guns...SMH
