Sig Special Edition P226

November 09, 2025, 01:31 PM

Does anyone remember a P226 from the 2000’s or 2010’s where the lower was basically a mk25 Picatinny lower and a standard milled slide and upper internals? Anyone know what the nomenclature was on that pistol was coming out from SIG? (Or am I completely crazy and that was never a thing)

Basically a P226 MK25 without the anchor, phosphate parts, and chrome-lined barrel? That most likely would have been a Special Configuration pistol (with “SP” in the part number). It wouldn’t have had a specific model name though. SIG only does these “SP” pistols when they need to move spare parts (meaning you end up with slide/frame combos that are off-catalogue). Essentially, these are factory “FrankenSIGs”.

I believe that was it. If I remember, the internals were regular parts but they may have been phosphated. I seem to remember the “SP” designation now that you’ve identified it. 226R-9-BSS-SP?

I believe it would be simply E26R-9-SP (maybe W26R-9-SP), but don’t quote me on that. The “BSS” would signify an all-black (B) pistol with night sights (SS), which it very well may have had. However, I don’t think Special Configuration pistols are labeled anything other than the model, caliber, and “SP”. Do you remember if the slide had the short or long extractor?

Short. It seemed to be the first gen of milled slides.

E26R-9-SP would be it, as MacGyver noted, if it was truly a factory Special Configuration gun.

I have a P226 with the short extractor, non-phosphate internals, non chrome lined bore and SIG's proprietary (vs. Picatinny) rail. The model number is WE26R-9-BSS-LGCY with a born-on-date of December 2017. There is no anchor while the slide is simply marked Sig Sauer P226.

Interesting. I looked at a used P226 with Elite slide (front serrations), no SRT, & factory threaded barrel. I had them pull the box from the back and it had "SP" on the Label. It had regular 2-piece grips but had the tool for the one piece in the box. Definitely a frankensig, but I have no idea what the factory did vs. the original owner.

Good to know what the "SP" means.

Therein lies part of the problem for determining originality. Since SIG only marks such pistols with “SP” and nothing else, any non-catalogued configuration could pass for “factory” when put in a box labeled “SP”, so long as the serial number and caliber match.

Agree.

There are a few exceptions, however.

1. If you are the original owner of an “SP” gun.

2. The NJSP stainless slide P228. Not original owner, but history is confirmed by factory and is documented.

3. The Afton Arms ordered stainless frame P228.

4. The Afton Arms ordered natural stainless P226.

5. The Afton Arms ordered Ilaflon P226.

(3), (4) and (5) were given the “SP” label by Exeter, after imported.

^^^That’s a good point. 1 and 2 especially. 3-5 at least have the benefit of having had all three main parts serialized anyway.
