I bought the .25ACP conversion for my Omega a couple of years ago before much else was available and personally I love it. I also have about several hundred .25 cases so that is not a problem. In addition to the improvement in the crud ring I like the convenience when handling the .25 brass over trying to handle the 209 primers. If I was going to do it again now I think I would still go with the .25 conversion although the suggestion to try the lower power 209 primers is a good idea also.
