So it arrived today.
Haven't had a chance to shoot it, but first impressions:
TM packaging is lovely, presentation is so well done, I now understand why everyone mentions it
Gun itself feels quality. I think most people wouldn't immediately know it was polymer slide if they picked it up. Not too heavy, but has a nice heft to it with the mag inserted.
Nice positive engagement when racking the slide, and the mag locks in with a positive deep click.
Controls all feel nice, although the safety/decocker is a bit stiff, but nothing difficult.
Overall I love it already. If it shoots half as well, then it's going to be awesome.
