If you really dislike the revolver that bad sell it. That extra 200 FPS makes a world of difference. That is why I now carry a 357 Sig. I have the best of both worlds, a 125 JHP at an honest to goodness 1450 FPS.
I was getting 1250 FPS from my 640 with 145 grn STHP and my SD was in the 5-10 fps range.
My rifle and pistol are tools, I am the weapon.
