I got one a month ago, loved it so much, I bought a second one.
The day I shot mine for the first time, I shot: my APX A1, Glock 17, an Sig M17, & a Colt 1911.
The APX A1 was my favorite, it really helped to have them loaded and switch back and forth shooting the different guns.
I’m gonna replace the sights on one of them with precision sights, just to enjoy shooting further distances with it.
As for the takedown lever, one of mine was stiff the first time I used it, rubbed a little Ballistol on it then worked it several times and it’s fine. One important detail is push on the button end of the takedown lever and simultaneously push down on the lever.
It’s a great system once it’s loosened up.
The APX A1 IMO the best polymer pistol on the market, for the price.
Great ergos, good “base” trigger, flat shooting, etc.
