I don't have a DeltaPoint Pro so I can't advise one way or the other, but I subbed to this thread because I'm interested in what responses you may get. I know the Leupold DPP is highly rated. A huge plus is the steel shroud that comes with it, protecting the polymer body & lens. The dot size is only 2.5 MOA, though. There are some among us here that find that problematic for fast dot acquisition. I'm currently shopping for my next RDS, and I'm strongly considering an RMR with 6.5 MOA dot size. Haven't made my purchase though, so there's always the RMR with 3.25 MOA dot.
