I want to get into pistol RDS eventually, but the time isn't right for me to invest in optics, proprietary milling of carry guns, and more rapidly depleting my precious ammo reserves.
Does it make sense to build a cheap inert training analog to develop certain skills in the meantime? I'm interested in the ability to practice things like dot acquisition on presentations, right and left handed, from awkward positions, in varying light, and while moving. I also like that inert training guns can safely be left sitting out 24/7. They can be picked up off a coffee table frequently throughout the day and used without having to worry about strict logistical safety protocol that real guns demand. I could probably put a lot of work in over 6 months or a year.
However, I worry that I may also deeply ingrain some bad habits without knowing better or having livefire feedback. That would be very counterproductive.
Sig makes an Airsoft RDS designed to go on a blowback p320 for $50. https://www.midwayusa.com/product/1022784595 I'm sure it sucks bad, but perhaps it could work in this application? I've already got a Ring's blue training gun at home with extra holsters that would accommodate a RDS.
Has anyone ever tried anything similar? Better ideas?
