I don't know who the DH is that came back with all the gibberish, but to answer your question.
About any of th scopes used for rifle or pistol will work fine.
You do not have to go with anything expensive and some of the Simmons and Tasco pistol scopes have been working on some of the guns that I have sold and helped with installing glass.
Some have also gone with Leupold or in one case, the Bushnell, pistol in straight 4X.
Look at some in your local stores to see how they are for your particular vision and also look at the eye relief on some before making yur choice.
Good luck and let us know what you decide, if you will.
