Just bought a 4506 from a pawn shop. Price was $378 out the door. No box or paperwork and just one factory mag. In very good condition overall. This one has German proof marks on it and the name Wischo stamped on frame in tiny lettering. I researched it and it was apparently exported to Germany through Wischo, which is the S & W importer for the German market. I suspect it was purchased at a US military base (PX or rod and gun club), and then brought back to the US. Serial number TDC 55XX puts it around 1990 production from what I have been able to gather from a couple of S & W info sites. I have a P90 ,P345, and a couple of Rock Island 1911's in 45 ACP but this is my first S & W 45 ACP pistol. Just wondering if anyone on here owns one and what kind of experience they have had as far as shooting it.
