Well I swapped out the straight backstrap grips and put the FBI palm-swells back on. Went out again yesterday and got to shoot about another 50 rounds through the 4566TSW. I am not sure if it the depth of the grip, but really need advice. The best I can seem to do in the accuracy department is to land 8 shots on a 8.5x11" piece of paper from 10 yards. I took my 5906 with me and can put all 15 rounds on the same size paper without nearly as much effort, not even using the Crimson Trace grips. Now when I shoot the 4566TSW, I have no confidence whatsoever, that I am going to hit POA. Hitting bottom, side and of 8.5" x 11" paper target. I've shot both a 1911, and a M&P 45, and found that I was more accurate with both. At this point I am really not sure where to go next. The gun functioned flawlessly, but for some reason I can make it land my shots. Any suggestions, or recommendations would be greatly appreciated.
