Finally, all of the serial numbers have been re-stamped to match. It should be noted that in addition to committing fraud by passing this pistol off as legitimate (assuming the seller did so knowingly), the ATF takes a dim view of re-stamping the frame/receiver serial number of any firearm, even if the original number is re-stamped. It is a felony to deface or change the frame serial number.

The following pictures allow a comparison of the size and font of the component serial numbers. Note that the number 7 has a 'tail' on the upper left part of the digit in the Times New Roman style font, vice the correct Arial style font. The frame serial numbers are seen below (click on the thumbnails to enlarge).

In addition to the font issue, the numbers on the faked slide are noticeably smaller than is correct.

The same font problem is seen on the barrel serial numbers.

Since an unserialized slide is hard to come by, the old serial number on pistol 8765 was removed by buffing or grinding. As a result, the left side slide rail is thinner than the right. This can be seen by the naked eye when the slide is removed and viewed upside-down. Measuring the slide with a micrometer verifies this.

An easy check that does not require any measurement or even removing the slide from the pistol is to check the clearance between the slide and the safety/decocker lever. Notice the much larger gap on the fake pistol because so much metal was removed from the slide when obliterating the old serial number.

Another clue is that when the original serial number was removed from the fake slide, it produced a sharp edge at the top of the left vertical surface of the slide. The other pistols have a much more rounded contour (as does the right side of the fake slide) where the side of the slide transitions to the rounded top half.

While un-numbered 'armorer's spare' barrels are much easier to come by than un-numbered frames or slides, it appears here too a serial number was removed as evidenced by the measurements below.

The locking block suffered a similar fate - its old number was ground off and a new one stamped (once again in the wrong front). Note the polished area where the serial number is stamped on the right side block.

In summary, while pistol serial number 8765 is an interesting study in counterfeiting, it is worth no more than 'shooter' price for use as a range gun or display piece. The majority of the signs that reveal this pistol to be a fake would be hard to see without a hands-on disassembly inspection (there were other signs that were not detailed in this article - no need to aid future counterfeiters). Some could be spotted if the pistol were for sale on-line and had excellent, detailed pictures. Unfortunately, this is not always the case. When buying a high-end pistol such as this one was alleged to be, the buyer should view the pistol in person if at all possible. If not, demand an inspection period. Caveat emptor!
