I have one of those little blue rubber practice guns I use to practice. I cut the hammer off so it better matches my 642.
I spend a lot of time walking around the house, shop and yard practicing.
You can get pretty dern quick if you work at it.
I can get it out but hitting the target keeps me in the high .50s, low .60s.
