I've had one for about six months.
A.) World's heaviest trigger. This makes it hard to shoot well, but is probably safer for me, since I carry it in my pocket.
B.) Mine won't tolerate the hot 115 grain +P 9mm's (it jams), so I carry 147s. I have not tried it with 124 grain +P.
C.) As light as an Airweight and easier to conceal, with 2 extra rounds.
D.) If I was buying a mini-9 to carry in an IWB holster, I would prefer a Kahr MK9. Better trigger, sturdier, etc. However, I think the light weight and stiff trigger make the Pocket 9 better for a pocket pistol.
