All I ever shoot is Duelist or GFer.
Went YEARS without short stroking my pistols.
Much prefer them short stroked. Not sure I am really any faster.
BUT. I did notice not having to do the whole ring around the Ruger anywhere
close to what I did before the short stroke.
You might find it different. I can only speak for myself.
You shouldn't have any problem finding someone in your local club that has some already done.
I'm sure they would be happy to let you try them out. See if you think it's worth the money to have done.
For me. It was.
