There are a bunch of things that I like about the Stealth Platypus. 1) The base pistol is solid, it is a 2011. 2) It accepts most aftermarket parts for 2011s, for instance I prefer larger thumb safeties because I ride them with my grip. 3) In our experience as a dealer, they have better than average customer service. 4) We have a pistol with over 50k rounds on it and have just replaced typical 2011 wear items like springs. 5) I personally like that it takes Glock mags. They are significantly less expensive than standard 2011 mags. 6) The ability to customize the pistol.
