Hello, I just picked up a Glock 19 -- it's my first Glock! Haven't been to the range yet, but am going to try to work in a trip this week. While it's been lightly used (< 300 rds) it's in near mint condition and came with a number of upgrades, including Trijicon sights, 3.5# connector, an extended slide stop and a "smooth" G17 trigger. Don't understand that last item, but am hoping to figure it out soon. Looking forward to learning a lot on this forum! p.s. I'm assuming the sights and connector would keep me out of the "stock" class at a GSSF match?
