I'm currently running a MatchDot on my HS Victor, and I love it. I'd buy another in a heartbeat.

That said, I am currently shooting a "cheap" (about $40) BSA red dot on my 41 mainly because I wanted to experiment and see how well a smaller red-dot would work.
It works well, and while I get a ghost dot image, I'm reasonably sure that it's because of my astigmatism and not the scope.

If you're forcibly frugal, the BSA is a good choice, but my next move for the 41 is to either go with another MatchDot or Ultradot (never a bad choice), or to try one of the compact red-dots which would most likely be the J-point.

I'm looking forward to the day when red-dot technology finally gives us a red-dot sight that ends up about the size of a Bomar open sight. Still waiting...
