The photograph on the left is a picture of the right side of the receiver with a stamp that no collector wants to see on a historic firearm that is in their collection. This is an importers stamp that is now required to be placed on firearms that have entered the U.S. after the late 1980's. On the plus side, every marking on a firearm will help to tell us its history and this importers mark is no different.
With this importers mark, we now know that this Manurhin PP came in to the U.S. some time after the late 1980's. This import stamp reads as follows, "C.D.I. Swan VT". This mark is what the law calls for except it would have been nice if the importer would have hidden this stamp under the grips rather then stamping it on the side of the receiver. This stamp identifies the importer as Classic Distributors incorporated, and tells us that they are located in Swanton, Vermont. The full name and address of the importer is Classic Distributors INC., Airport Rd Bldg 2, Swanton, VT 05488 and the telephone number was (802) 868-3715. The import law that is mentioned above can be referenced by viewing the gun control Act of 1968, Public Law 90-618 and under Subpart F-Conduct of Business sub-section 178.92 (a)(1) Firearms.
The photograph on the right is of the Manurhin PP in a period holster that I found for sale at one of the online auction web sites. It is nearly a perfect fit for this pistol.
How to field strip the pistol.
FIRST MAKE SURE THE PISTOL IS NOT LOADED.
1. Pull down on the front of the trigger guard which doubles as a takedown lever and push it to the right. It will rest against the frame and remain open.
2. With the trigger guard pulled down, pull back on the slide as if to put the pistol in battery.
3. With the slide at the end of its rearward travel, simply pull up to remove. Total disassembly time is about 15 seconds.
