I went to the range in here forest park, ga and shot 100rds with my 40 tact. I got all my shots in the silhouete, but not a grouping together. I notice all my shots seems to hit left. I need some help with my shooting and grouping. When I fire my xd I hold the trigger until the gun finishes recoiling, but to correct the leftside shooting should I use my first knuckle because I'm currently useing the second knuckle. On the second box of fifty I have been hitting my mark. If anyone here lives close to the range i would like have a range buddy so I can get better at this, thanks guys.
