I like mine a lot. Lessons learned as follows..
If you haven't already, get some oil onto all the right places, especially those that help ease the trigger pull. Carefully feel the tip of the trigger safety to see if there is a tiny molding burr on it, and if so remove it with a few wipes of an emery board. Unless you like the stock Glock sights, try using a marker to black out the rear sight - I found that works better for me. Try out the backstraps and use the one that results in your trigger finger having a 90 degree angle at biggest knuckle joint (without any backstrap you'll have a small size grip). The Glock sport holster ($15) works well for OWB carry.
500 rounds so far with zero stoppages, and just one failure to hold open at empty mag (but that might be my grip impinging on slide release).
