I played around with a Nano a few weeks ago. Didn't like the feel.
Also, there is no slide release, which seems odd to me. I know some folks who don't have issue with it, but it just didn't "feel" right for me.
I was researching these recently, and came across a number of articles and posts on forums with folks having issues with FTE using various brands of 124 grain. Again, might have been an issue to a certain mfg date range, while others may never fire 124 gr.
For me, it wasn't originally in my top 3-4 CCWs, and after handing it, seeing the issues online about FTEs and the slide release item, it just turned me off completely.
So, to be fair, I was already thinking "no", so I went in moderately biased, and a few negatives, at least to me, killed it.
