I've had good luck with 2 different PM-9s that were manufactured 14 years apart. One of these guns I ran through part of a handgun class.
I have heard differing things about PM-9s over the years but I don't know anyone personally who has had a bad one or had an experience in having to send one back and go through all of that headache.
I am glad that I do not have a lathe at home, because I have had bad experiences with certain guns that would have resulted in my slicing them up.
