I got mine back today. Received a call from my FFL around 3:30 pm CST telling me it had arrived. Stopped by after work and started filling out paperwork. In the package was a new retail box containing my R51, two mags, a new lock, and manuals; a box containing a pelican case; and a plastic bag containing two more mags. So add those to the two they told me not to send back and I've now got 6 mags. I wanted to clean the gun and properly function test so I brought it home with no rounds through tonight.

I forgot what a bear this thing is to disassemble and reassemble. But everything seems to be working properly. The slide does feel much smoother than what I remember in my original which was very stiff and clunky along the way. The trigger is now plastic opposed to metal as before. I'm not sure why they skeletonized a plastic trigger but it looks nice enough. Not much take up and comes back to a stiff but clean break (not sure weight yet) at prob 6-8lbs. Reset feels long but not bad with no audible click a just the slightest feel. This could still use some work. But I'm sure I'll get the feel for it on the range.

I was a bit disappointed in the fit and finish still black coating out of the box was scratch on the edges of grip safety and there's a gouge in the edge of the spring bushing. Finish also missing from 2points of checkering on front strap.
