I seem to be able to shoot my 1911 when shooting with deliberation, but when shooting from the holster, even with a more lax pace, I pull to the left when shooting right handed ( my strong hand ) and in a more traditional modified Weaver using both hands. I've played with finger placement on the trigger and same results. Now to make this more confusing, when making head shots from ten yards, I'm OK, but my body shots are all grouped about five to seven inches to the left of my intended impact. From a sandbag, the Valtro groups very nicely at 15 yards. I am shooting in the SF Bay area, so there might be some area related tendency to shoot left. Oh.. sorry.. correction.. the tendency is to retreat and declare victory.
