I purchased the comparable holster with the 15deg cant for my PT-111. I have noticed that it does tend to print a little more than I thought it would, and I do think it is due to the cant. (Of course, this is the only holster I've bought for it, so I don't have a baseline for how others print.)
Not only does the grip jutting out tend to print under my shirt, but the cant also causes the barrel end to print on my 'cheek'. Obviously,this is fairly easily remedied by sliding it further around the back, but I'd prefer it closer to the side then so close to the small of my back.
I should also note that I haven't bought a completely new wardrobe, and haven't tried fairly heavy shirts. (I've yet to get my CHL, so wearing it has been relegated to around the house so I get comfortable with it for when I do get my CHL

)
I've been contemplating getting the one w/o cant anyway.
