It really depends on what you're going to use them for. If you just want to punch holes in paper, either will do. For competition, the heavier bullet with a lighter load will create a little less muzzle flip. For SD, I prefer the 124 GFDHP. The 124 GDHP seems to have a large following and in my own (not too scientific (water jugs) test, they prove to be everything that this site claims: Pistol Cartridges (9x19mm Luger)Is their any appreciable difference in your experience of research?
Be sure to report back on the accuracy of those Dold Dots.:razz:The owner and instructor at TDI here in Ohio has stated that 124 grain and 124 +P are the most common SD loads he sees at the school. I am planning on getting 124 grain +P Dold Dots when i can get them.
