I agree with all of the complaints listed above. It's too bulky for a 9mm design that can't ALSO be a .45 design. It has a long DA pull. I don't like 'positive' slide-mounted safeties. I do NOT like the grip shape.
Having said that, I could conceal it just fine if I had to. While I don't like the DA pull, I don't really ever plan on using it, the vast majority of the time I think I will have time to cock the hammer. And while I might not PREFER the positive safety or the DA pull, I know how to operate both just fine. The SINGLE action trigger is about as good as it gets. The bulk and weight make it very stable to shoot. I remember the first time I shot one, I couldn't believe how it bounces right back to the point of aim as you shoot it rapidly. As a service arm, I think there are more durable options, but if you test it, and it works, and keep it clean and check it frequently it will be fine. (My main complaint about it as a sidearm is the NATO ammo. If I were allowed to use 147 gr jhp ammo I would like it just fine.)
I just shoot 1911s better. And I don't rely on handguns for HD.
