After years of SA pistol use only, I decided to renew my acquaintance with DA revolvers.
Rather than dry fire a revolver with dubious feedback results, I got one of these.

It has a rifled barrel for lead pellets and is very accurate with realistic action and feedback from holes in an actual target.
It works great and provides a lot of trigger time right at home.
P.S.
I'm on my second one, having plumb wore out the first one.
