I have been wanting one of these for years and with the recent flow of PSPs into the country I thought it was time to finally pick one up. I called the local gun shop today and was informed three PSPs had just arrived. I stopped in later and purchased what I thought was a PSP. The gun is marked HK P7M8 though it has a heel magazine release. Is this a PSP or some type of hybrid? The serial # is 738xx and I believe it had a manufacture date of 1986 on the slide. Any help figuring out what I purchased is appreciated!
