Just bought my Glock 20 about 2 weeks ago and soon realized I wanted something a bit more different and stumbled upon the pictures of all these long slides. So low and behold received my long slide assembly. It's a LWD assembly with burris fast fast sight. Took it yesterday to the range to try and just shoot the gun without sighting in the sight since I didn't have time. Didn't bring any ammo with me so I bought some from the LGS, they were 50rds of american 180gr FMJ and all ran smooth as heck! The sight was dialed in pretty good already from the factory, maybe just a smudge bit of adjusting. I am super happy with this thing, everyone at the LGS were oohing and ahhing about it. I'm sorta digging the two tone, but probably will end up shipping to CCR or some company that will make it a matte finish. Here's a quick pics of it, not the best sorry.
