Glock 19 has been shooting to the left since I installed my Warren sights and I finally adjusted it this morning and put 50-70 rounds through it. This is my best group at 15 yards with any gun. Also had my first stovepipe. Glock 19 Warren 2 dot sights Glock 17 trigger and trigger bar 3.5# Lone Wolf connector NY-1 Olive Trigger Spring ZEV Tech Titanium Plunger ZEV Tech Reduced power Firing Pin Safety Spring ZEV Tech Reduced Power Firing Pin Spring WWB ammo Also had a brass pop me in the head. It's happened before and I thought it was because of the stainless guide rod and 13# spring so I put the stock one in. The flyer on the right was when the stovepipe happened.
