Well, again tried both my G19 and G34 today with same ammo, same results!! Both benching and shooting offhand at 25 yds. The G19 will keep all hits in the black area of a std. bulls eye target. The G34 still puts hits all over the entire target. Others have fired the 34 with same results. Have to admit the triggers in both guns are a little different in pull weight, and thinking back that when I first got the 34 and then had the barrel lug built up, the gun shot well. I really don't have that many rounds thru the barrel so I would think the barrel is not worn out at all! Having the barrel lug welded and then refit did help alot with the play in the slide and locking block and the gun functions fine. There is very little difference in grouping even when I put my KKM barrel in the 34.
Really don't know what to do next with the way its shooting, maybe sell it!!
