I've had my 30s for about two months and love it. For me it was accurate from the first shot. I shoot it significantly better than the G17 I also have. I have medium hands and being a double stack .45, my first, I expected it would take some getting used to but it felt natural and hit right where I aimed from the first time I pulled the trigger. Out of the box, the trigger broke at about 7.25 lbs. I swapped the connector for the Gen4 "dot" version which dropped it down to about 6.5 lb. Swapping the trigger spring for a 6lb competition spring dropped it to 5.5 lb.
The 10rd magazines, though, will take some work to get that last round in, even with the supplied loader. Even then when full they are very difficult to seat fully in the frame. Don't be discouraged as all they need is a little break-in time. I've since bought additional 10rd and 9rd mags and the first thing I do is disassemble them and make sure the coils in the spring are all aligned correctly (one of mine was slightly twisted). Then load them fully and let them sit for a few days, occasionally unloading and reloading them. The 9rd mags I got last week were *impossible* to get the 9th round all the way in even with an uplula loader pressing down as hard as I could. Within two days, I could seat the 9th round by hand. And all magazines when full easily seat in the frame with just a little push (ok, maybe a sharp rap with my palm).
