The 9 mm Luger cartridge shown appears to be the MAP (Maximum Auto Pistol) loading.
The bullet is similar to that of the .380 MPP (Maximum Pocket Pistol), and may have been renamed since at the time these were made in the mid-1980s, there were few 9x19 mm pistols that one would call a pocket pistol. Today, of course, they are legion in number.
In all the literature I have on this line of ammunition, the “MPP” designation is only applied to the .380 Auto Cartridge. My catalog-sheet file for this company is far from complete, so as I say, it is not impossible that when the 9 mm was first introduced in this loading, that is was referred to as the “MPP.” I simply don’t know, so must go with the information at hand.
This ammunition was the product of Personal Protection Systems Ltd., not out of business but originally at 101 Pittston Avenue, Scranton, P 18505. The principal figure in the business was one Aron Lipman.
From their literature: "The MAP is loaded with a pressure designed light weight pure copper projectile - hollow point with a pure nylon cap which is hollow inside to accept PPS’s expansion system, whereby, the projectile upon impace expands up to .70 caliber, yet still has excellant tactical penetration.
"At near maximum SAAMI pressure, the 67 grain MAP projectile produces a muzzle velocity, depending on barrel length, in excess of 1700 FPS, up to 1850 FPS. IN addition, the nylong cap guarantees 100% feed reliability in all quality 9 mm semi-automatic pistols.
“Because of the light weight projectile the MAP is not recommended for gas operated semi-automatic pistols.” (HK P7???).
The above information from a single sheet advertisement dated December 29, 1986.
I will withhold my personal opinion of the veracity of the claims made for this cartridge, and others in the same line of ammunition.
