I had one for a little while, as I always state, if your going to go Para, go stainless, the Parakote doesn't hold up well.
I liked the Hawg, but it was incredibly unbalanced with the setup I had at the time, if I had a different holster, I may have kept it.
All I can say, is that you'll need a holster with a lot of space between loops if you go IWB, as the gun is top heavy when holstered. The butt of the gun is kinda wide, but if you're used to a double stack gun, it shouldn't be a problem.
Mine was super reliable, and the fatter grip did make the gun more controllable IMHO it was one of the better shooting and handling 3" 1911s I've ever shot.
One thing I did like about it, is that I could carry a 14rd P14 mag and use that as a reload, that was a very nice option.
Originally I had it has a partner to my P14-45 LDA, due to being able to use the P14 mags in the Hawg. I found my P14 to cumbersome for carry, sold it off, and the NiteHawg soon followed.
I miss them both.
