I have a P320 Carry with #6 Front and #8 Rear. I've been having issues with shooting low and left (anticipation) and it's terrible when I use my 320. Last week I went through a trial run of the FDLE course with a S&W M&P 40 and shot significantly better and wasn't even close to being as bad as shooting with my 320. My shots were still low and left but out of 50 rounds I actually managed to get 10-15 rounds Center mass and that's something I'm having difficulty achieving with my 320 where I just can't seem to get. Besides having to work on my basic skills with my firearm, I heard on an early post that having a #6 Front post was too tall for the #8 Rear. Along with that, I was also wondering if I'm supposed to hold my sights at a 6' o'clock position or a combat hold? I'm really confused with this and any advice would be really helpful.
