If you are 6'5", I think you will find 14" LOP to be short for you.

Here in the UK we see few German shotguns, but those we do see are respected for being well built and having fine handling. I have not heard of many problems, but getting spare parts (if needed) can be a problem. I ended up having to have parts made for my Merkel 303, which is expensive.

I have found that triggers pulls tend to be set on the heavy side with German guns.
