Purchased my first Glock this week and got to shoot it today. I cleaned it prior to shooting and it ran without any hiccups. However, my accuracy with it was not great. It wasn't until after 150 rounds that I was able to put 3 shot groups under an inch at 7 yards, but that was super slow firing. Whenever I shot rapidly or as soon as the target was reacquired, everything went pretty much low and to the right. I dry-fired a bunch right there at the range but the results were the same. Accurate as slow fire, trending towards terrible at faster rate of fire. My point of reference is shooting my FNS-9, with which I am a 1.5-2 inch group shooter at 7 yards. I know it takes practice with a new gun, but this outing was rather disappointing. Any advice on flattening out the 'ole learning curve?
