So I shoot my g17 horribly. I went to the 5 yard range to just compare what was happening with my Beretta 92 and Sig 229. Every dam grouping is far low and left so I assume it's the heavy trigger pull. My other handguns do this slightly (I'm working on it) but my Glock is just 4 inches left which tells me it is likely the trigger?? Maybe the sights? Maybe I ought to sand bag it and check.
