NO offense intended, but this makes me think you haven't been shooting long or haven't done much study.
Every serious shooter I've ever talked with or read espouses the value of dry fire. Many of the best shooters report 50:1 and up dry to live practice. This matters when your talking about guys that shoot thousands of rounds per year. Partly it's a cost thing partly it's training your body where you can break down and isolate minute movements w/o the confounding of recoil. Partly it's just repetition. I recently was reading a bit from a world champion who said at some point on range days he feels a deterioration with live rounds and needs to return to dry practice to maintain top form.
My own very limited experience with an air soft pistol was that it was to inherently inaccurate/variable for anything but speed work on large targets. Perhaps high end guns are better. For training gross movements, movements and trigger discipline i.e. Finger off till on target they are fine. The more finite your training goal the more problems you'll have I think.
My range doesn't allow draw from a holster either, but my home does. I unload- verbalized to myself and double check then do a bit of holster practice.
If you really want to get good then it's a whole different game. Gotta train and work on each little part then putting it all together. Draw, grip, sights, trigger, recoil, follow up, malfunctions, awareness etc etc.
Good luck and enjoy the process, it's a big challenge but I'm having fun along the way.
