I just picked up a new Gen4 G17 and took it to the range last night. It seems to shoot to the left. The only mods are a Ghost 3.5 connector and Warren Tactical Sevigny Competition sights. My friend and I are decent shooters, and can consistently shoot a 2" or less group at 15 yards. I have Gen3 G26 and G19, so I am familiar with the trigger. I saw my shots were going left, so I slowed down and concentrated on my trigger control - same result. I then moved the target out to 25 yards and shot bench-rest. I took 3 slow shots, and watched my breathing, hold control trigger control etc. My shots ended up touching each other and about 3" to the left of my POA. Then I had my friend shoot it bench-rest and he got the same result. The sights were installed by a local shop and look to be dead center. Is this a known issue? What could be causing this?
