The purpose of this thread is to organize more detailed information on the Heckler & Koch SR-9 series of rifles than what is commonly available elsewhere. If you have more information to add or correct, please post and it will be consolidated here.
- All SR-9 T and SR-9 TC rifles started out as SR-9 rifles manufactured in W-Germany, and stamped, "Made in W-Germany
HK Inc. Sterling VA." The serial prefix is 46. They were all sold in the U.S. market. According to H&K, 3000-4000 were produced. Serial numbers suggest closer to 4000. The "T" and "TC" stamps were all hand stamped on SR-9 rifles by H&K USA as they were ordered.
- The very first SR9 rifles shipped with the black polymer HK 911 Bell & Carlson thumb hole stock furniture and a set of black HK 91 furniture. Later SR9 models shipped with the same thumb hole stock but were painted in the wood-grain pattern, which had been advertised as the Orion. At about serial number 1,000, H&K began using black thumb hole stocks again. The thumb hole stocks included an SR9 specific polymer strip which attaches to the front of the hand grip with two screws and had MSG90 buffers installed. For a short while after the switch back to black thumb hole stocks, HK increased the SR9 price and included an HK91 hand guard, grip, and rear stock without buffer or hardware.
- There are claims that the first SR9 rifles ordered in T or TC configurations were not hand stamped at all. But, absent model number documentation from H&K such as an invoice or packing list, these claims are unsubstantiated because there is no known way to tell unstamped rifles apart from upgraded SR9 rifles otherwise. If anyone has H&K documentation of an unstamped T or TC, please post it. There are reportedly 25 unstamped "TC" models and another 100 stamped, but whether the unstamped rifles were ever officially considered TC models by H&K is unconfirmed. H&K has said they sold about 125 TC configured rifles in total though. The number of T models is unknown. Apparently, HK no longer has records of which SR9 serial numbers were factory upgraded to T and TC models or the information is not readily accessible or filed away somewhere.
- Later T and TC models had a PSG1 trigger warning sticker in the SR9 manual as such (some of these labels may have been attached elsewhere):
- Receivers date coded KA-KD (1990-1993) will typically have slightly older barrels date coded JA-JB (1990-1991), and bolt carriers dated II-JA (1988-1990). The bolt heads are usually newer and closer to the receiver date codes, i.e. the KD (1993) rifle photoed has a JC (1992) bolt. Stocks should also be in the same date range, the one photoed is coded JB (1991). Date codes may vary, but obviously, a date code which is later than the dates of manufacture would indicate it was added on later and is not original.
- There are three strong motivators for people to counterfeit the "T" and "TC" stampings, so care should be taken when purchasing for any collectible value above and beyond the parts;
- The originals are hand stamped, irregular, and thus easily counterfeited.
- Counterfeiting dramatically increases the perceived value and prestige of the weapon.
- T and TC models were allowed to have PSG-1 and MSG90 lowers and stocks rather than the SR9 thumb hole stocks.
- Absent documentation from Heckler & Koch, such as an invoice, packing list, or label, it is practically impossible to prove a factory T or TC rifle, but as noted above, there are several things that should be considered;
- PSG-1 trigger warning in SR-9 manual.
- Date and proof codes consistent with known factory T and TC rifles.
- T & TC stampings consistent with known H&K stamped rifles. The stamping should penetrate the original paint. The font and size of characters should be consistent, alignment is insignificant - there are bad stampings, but the visible portion of the stamping should be consistent in font and size to known H&K stamps.
- Here are some examples of stampings consistent with known H&K stamped rifles and some that are suspected to be counterfeited for comparison. Keep in mind, the quality of the hand stamping is unimportant, it's the font and size that matters, but never base a decision on the stamping alone because it's the easiest element to counterfeit:
