With all the talk about dry firing, I haven't noticed anyone bringing up adding a Crimson Trace, or equivalent laser to their J-Frame. I have and have found that absolutely necessary for determining how one's tendency to jerk/pull to the side/up-down when pulling the DA trigger. I even added a CT to one of my L-Frames.

It doesn't take much time at all to actually pay for the CT-laser, by counting just how many rounds have "NOT" been shot. And the bottom line is that you can remove the CT-laser grip after you perfect your trigger pull. After all, it isn't like tattooing a big 'ole "L" on your forehead...
