I've been looking for a either a swiss K31 or 1911 for a little while. I saw that classic firearms has the 1911 in stock.

From the searching I've done so far it seems that some people have had pretty bad experiences while others are happy so I just wanted to see if anyone on the board has feedback for me. I'm always a little nervous about buying a used rifle with out inspecting it first and I don't want to shell out 500 clams for a wall hanger. 

As long as you are not buying a so called “collectible” K98 Mauser from them you are probably good.

As far as what to expect? I would expect that the longer that specific surplus weapon has been available expect the quality/condition of what is available to get worse.

Familiarize yourself what. NRA good is.  The rifle will be complete and most likely shootable but not pretty.
