This is my second Bianchi 100. The first I got years ago for a S&W and it held up really well and this is the reason I got one for a Hi Power.
The leather is sturdy... not so thick that it's bulky, and not so thin that you can feel hard metal edges against you.
I think it "could" be made a bit shorter as the barrel has a bit more room up front than it needs making it go deeper into your pant than needed but, as it is, it works.
The cocked hammer is well protected from rubbing the skin, and the mag release has sufficient clearance from touching leather so that it will not inadvertently be pressed by the leather releasing the mag. Also the grip rides high enough that a fast grab by the hand will be sufficiently high up on the grip of the handgun.
All are important considerations for a correctly fitting holster.
