I think they are great guns. I recommend them when asked to recommend a shooter Luger. Mine is extremely accurate. It did require some break in rounds before it became reliable. I use the 124 grain NATO load from Winchester in mine. I also purchased some of the current manufactured MEC-GAR mags from Brownells. They work well.

Here is a great article on the history and development of the interarms guns:

I shoot this one regularly. Keeps the wear and tear down on the vintage guns.
