Just picked up a Glock 34 Gen 5 for USPSA Production, and I'm looking to tune it up a bit. Currently, my only handgun is a 19 Gen 4. I've got a ghost connector with the over-travel stop tab, ghost trigger spring and firing pin safety spring. I've polished up the face of the striker and the end of the trigger bar, and I'm pretty happy with how it feels, especially for a carry gun. I currently have Sevigny Performance sights, fiber front and plain rear. I was planning on doing the same work to the trigger on the 34, but I'm open to hear what everybody else has done and the results. On sights, does anybody run sights that hang over the MOS cover plate? I likely won't ever run an optic on this gun, and I just want to know if there are any downsides (besides looks) to overlapping the plate. Also, how are the factory 10rd mags limited? I got 3 of those and 3 of the 17rd with it, so I was wondering if I could turn them into 17rd since I live in a free state.
