My friend picked up his (wife's) LCR .38 yesterday and we shot it a bit with some Remington 130 grain fmj. I had no problem keeping them all in a 3" bull at 10 paces by just pulling the trigger straight through. My friend, a single action only shooter, was trying to "stage the trigger" by pulling almost to the fire position, correcting his aim, then finishing the pull. He was all over the place with that technique. Some shooters with some revolvers can do good work that way on the range but it's a poor practice since in a real life and death situation you'll never have that sort of fine motor skill.
Anyhow, the LCR was plenty accurate enough for its' purpose, shot to POA and recoil was quite comfortable with those Remington loads, I'd say about like my 6", with full .357 loads, though not nearly so noisy. He plans to load 125 grain Gold Dots for her, starting light and working up to +P if she can handle it.
