I have a Masada Slim and really like it. It shoots great, has a good trigger, and very mild recoil for a gun this size. I've owned and shot Glock 43, 43x, and 48, Shield Plus, Hellcat Pro, and 365. The Masada slim is the only one I still have.
Less recoil than the Hellcat. Shield grip shape on back dug into the web in my hand. Glock had crappy glock triggers. 365 was too small in the grip. Masada Slim covers all of that for me.
Like other previously posted it can take Jericho mags. I was able to very slightly widen the feed lips on full sized Canik mags and they feed 100% so far. They don't lock the slide when empty tho.
My only complaint about the Masada Slim is the take down method. Or rather reassembly method. Getting that pin in and lined up just right can be a pain in the ass.
For the larger Masada. I had one of them too. Single complaint is the grip was pretty slick. Other than that it shot and functioned just fine. But it kind of bored me and didn't do anything any better than anything else.
