I just reviewed some fired rounds from a gel shoot where it was fired from someone's J-frame. The expansion & penetration actually rivaled that of some of the 9mm rounds, including the 127gr +P+ load. It did well in the denim-covered gel block and the auto glass shots, comparatively speaking. Interesting.
I've got it in one of my J-frames at the moment. I might make a quantity buy a little later after seeing how it did in the gel shots.
Of course, I have other loads in other J-frames, depending on what's closest at hand when I'm loading the guns, speedloaders & speedstrips. I think my present +P loads include Speer 125gr +P & 135gr +P, Rem 125gr +P GS & 158gr LHP +P and a couple of different standard pressure loads for a 37-2. I rotate the different loads out for qualifying & practice with different J-frames, but I haven't seen much difference in POA/POI until I start to get out past 10-15 yds ... in my guns, in my hands.
