I got a 22lr slide for a 40sw sig for $300 and paid for it in about 3 trips to the range and a few thousand rounds. Benefit, it stovepipes all the time so it lets you practice failure modes all the time. Very worth it. I swap between it and real rounds to keep myself from getting recoil-shy.
I'd also recommend something like a mantis-x which lets you practice smooth trigger pulls while dry firing. It's actually a pretty smart bit of tech, it's all based on the one of the solid state accelerometers like you have in your phone.
I was thinking this would be something similar to the trigger squeeze and breathing monitors I used with weapons training VR, but this actually looks like it would be really useful, and very data driven. Appreciate the info!
