I have had a p89 for about six years now, I love it!
It is made for big hands, built like a tank. Long trigger pull, big slide comes back like a hammer. If you are looking for something a french girl would shoot, this isn't it.
I have not once had a failure to fire, always been very smooth, and I wouldn't doubt you could bore the barrel out to a .500 smith and it would probably still shoot it, the thing is built like a tank.
VERY accurate. The 9mm in a gun that big can make soda cans dance all day at 15 yards.
Overall if you are into big frame guns that work and will eat anything, its a great way to go.
