Hi-caps for the USP45F are all stolen US Government property.
The following is from the HK-PRO web site:
What follows is a letter from Jim Schatz of HK's Federal Operations department, to Small Arms Review magazine (Feb. 1998) in reference to their position on unmarked high capacity magazines. This subject has stirred much controversy. HKPRO is in line with Heckler & Koch; I will not accept classified ads for unmarked high capacity magazines for the USP45 or SOCOM pistols. --HKPRO
Dear SAR:
The second issue of SAR looks great, however an ad in your November classified section regarding the sale of "pre-ban" H&K SOCOM 12 round magazines annoys me. Other "dealers" around the country have been offering these mags as well. This may be a good subject to address in your reader information pages.
There never was any such animal as a pre-ban high capacity (12-rd) SOCOM pistol (MK23) magazine! Regardless of what anyone says, these magazines are simply stolen U.S. government property! The production contract for the MK23 pistol and all the spare mags was not even awarded until June, 1995, after the Crime Bill was enacted.
The MK23 contract called for the U.S. Government-ordered magazines to be delivered to the U.S. government without the Crime Bill markings, with an exception granted by BATF of course. This is how the more than 20,000 magazines ordered and received to date after May, 1996 by the U.S. government in support of the 1,950 MK23's purchased were delivered.
The 12 round Mark 23 magazines that we order and stock here for general sales with "commercial" Mark 23s to law enforcement and military customers are marked with the Crime Bill markings as is required by law. The exception was/is only for those weapons delivered to the U.S. government.
There were never any USP45 12 round magazines made intentionally without the Crime Bill markings. While it is possible to insert magazines of the MK23/MK23/0 in the USP45 (not vice versa due to the different floor plates), these magazines are different and should not be interchanged. The feed lips and floor plates are different between the two magazines. Swapping these magazines can reduce the reliability of the weapons when the incorrect magazine is utilized.
You may wish to inform your readers that if they buy (or sell) 12 round unmarked magazines for the MK23/MK23/0, they are buying/selling stolen U.S. government property, plain and simple.
If their claim is that these unmarked magazines were produced prior to the Crime Bill and imported through another source besides HK, Inc., that's a lie as well. If their claim is that the magazine housing is a USP45 pre-ban with a MK23 floor plate fitted to it, that's also untrue. Ask the "dealer" his source for the magazines in question and see what his response is.
While there could be a few (less than 60) prototype 12 round unmarked SOCOM OHWS (Offensive Handgun Weapon System --HKPRO) Phase I or Phase II magazines floating around, most of these were delivered to the U.S. government with the prototype pistols (except for a handful that we kept here) and were thus purchased by the U.S. government and are thus U.S. government property also. However, the Phase I prototype magazines do not fit in Phase II or production Mark 23s or USP45s.
I have inspected one of these so-called pre-ban magazines actually purchased from one of these "dealers." It is in fact one of the mags we sold to the U.S. government on the contract.
Be advised that the Naval Criminal Investigative Service (NCIS) is aware of this issue and have an ongoing investigation into the loss of this controlled U.S. government property. Buyer/Seller beware!
