I was doing this with my H&K striker fired pistol. It was my front sight hold and I was jarring the trigger a bit. I sorted it out in three boxes of ammo as a new shooter so I am pretty proud of that, still a few flyers here and there I have to work on but my targets look like somewhat of a grouping now. I started covering the bullseye completely with the front post and it really helped me out. I forgot how difficult the short sight radius makes things from shooting rifles all my life. Still want to put another 500 rounds or so through the gun before moving onto my SA/DA guns. I figure if you learn to shoot on a striker fire, a hammer gun should be a little easier. Could be wrong though, we'll see.
