Update, after further research, the PDX1 has 6 petals to the Rangers 8. Apparently the Ranger line is being discontinued as the PDX1 is an improved round. I downloaded a pdf from American Rifleman comparing the PDX1 vs the Critical Defense. Both are considered to be the best out there, with neither having a distinct advantage over the other. The PDX1 performed slightly better in ballistics testing using gelatin, glass, steel, drywall, &plywood. The CD performed better in the plywood testing portion. Now if only I could figure out how to upload the pdf!
