3.5 connector supplied and installed, contact points polished for a much smoother, lighter pull. Price is $69. The lower frame is needed.
Full size Glock accuracy upgrade, this modification keeps the barrel locked up in the slide during firing for a significant group shrinkage. A small precision weld is applied, and fitted to the bottom of the barrel rest pad. In stock condition the barrel has a lot of up and down play. Price runs $39. The complete pistol less the magazine is needed. Gen 4 versions don't usually need this modification, Glock has really improved the barrel lock up over previous generations.
I did this modification + trigger work to my Glock 20, 10mm and can dance 1 gallon milk jugs at 100 yards.
