When I'm tucking a shirt into dress pants; I reach for my G42 and wear it IWB at 4 o'clock 9 times out of ten.
It's light.
It's thin.
It prints less than any other gun I have.
It's also very easy to empty the mag on target. It's virtually got zero recoil! This is not a blowback weapon. Moreover, though not that much bigger than an LCP, it is just enough bigger that you can handle the thing. Of course, that lack of recoil is also because it's a .380. If you can live with that, give it a try.
Just so you know, I bought all kinds of single stack 9's to wear when I went to work. I love them all and they work. But not one of the nines comes close to the G42 with respect to ease of carry. The Beretta Nano bless it's little heart was close, and I might be singing it's praises if it didn't act like such a cow and jam up all the time. Yeah, bar none, the G42 is one easy carrying little pistol. I carry it often.
