Okay,let me try to explain in a bit more detail.
The pistol I'm using for this discussion is a Smith M&P c9 with the medium grip swell. No lasers or lights, etc., and bone stock for now. A trip to Bowie Tactical is in the future. I was using Wolf 115gr ball ammo for this session, 200 rounds worth, and one (12) twelve round clip of Black Hills 124 grn HP at the end. Pretty much dead on with the latterat about ten yards. Hearing and eye protection was used, both ear plugs and Mickey ears. And at ranges varying from 7+- yards to 50+- yards using a "dirty bird" type silhouette target.
As stated earlier, different grips and finger placements were used with varying degrees of success.
Where my problem is, was that even though all but one or two flyers, due to total loss of concentration on my part, were within the center mass area of the target my "anticipation" was causing me to make continuous though unintentional heart shots instead of sternum shots. Where I want to get myself to be in terms of accuracy is quite simple. Thirteen continuous head shots at fifty yards.
Since I'm normally by myself, as said before, it's hard to get feedback from others to tell me if it is a flinch. I don't feel as though it is a flinch but, more of a reaction to the recoil itself. Just in advance of it. I know when the trigger is pulled back to "that" certain point, the pistol is going to go BANG, and there will be pressure pushing back at me and the muzzle is going to move upward a bit. But, for some reason, that alone is effecting my shooting.
