They are wonderful. Drawbacks might be sometimes they have cheek pieces and sling swivels. Cheek pieces are fine if the gun fits and sling swivels are a little ugly maybe but can be very functional. The guns are often plain but the older ones, even the most-plain ones are incredibly well made. I noticed Hill Rod & Gun has at the top of their web page one that looks like a nice German 16 (I don't know if it is a Simson but just for comparison).
