[PursuitSS]

I just noticed that the ONLY markings on my PS90 receiver are the caliber, model, and serial #

CFR 478.92How must licensed manufacturers and licensed importers identify firearms, armor piercing ammunition, and large capacity ammunition feeding devices?(a)
(1) Firearms. You, as a licensed manufacturer or licensed importer of firearms, must legibly identify each firearm manufactured or imported as follows:
(i) By engraving, casting, stamping (impressing), or otherwise conspicuously placing or causing to be engraved, cast, stamped (impressed) or placed on the frame or receiver thereof an individual serial number. The serial number must be placed in a manner not susceptible of being readily obliterated, altered, or removed, and must not duplicate any serial number placed by you on any other firearm. For firearms manufactured or imported on and after January 30, 2002, the engraving, casting, or stamping (impressing) of the serial number must be to a minimum depth of .003 inch and in a print size no smaller than 1/16 inch; and
(ii) By engraving, casting, stamping (impressing), or otherwise conspicuously placing or causing to be engraved, cast, stamped (impressed) or placed on the frame, receiver, or barrel thereof certain additional information. This information must be placed in a manner not susceptible of being readily obliterated, altered, or removed. For firearms manufactured or imported on and after January 30, 2002, the engraving, casting, or stamping (impressing) of this information must be to a minimum depth of .003 inch. The additional information includes:
(A) The model, if such designation has been made;
(B) The caliber or gauge;
(C) Your name (or recognized abbreviation) and also, when applicable, the name of the foreign manufacturer;
(D) In the case of a domestically made firearm, the city and State (or recognized abbreviation thereof) where you as the manufacturer maintain your place of business; and
(E) In the case of an imported firearm, the name of the country in which it was manufactured and the city and State (or recognized abbreviation thereof) where you as the importer maintain your place of business. For additional requirements relating to imported firearms, see Customs regulations at 19 CFR part 134.

All of the information is there, just not on the upper.

 

[Fallschirmjäger]

The serial number, model, and caliber are all on the receiver (no upper or lower on a PS90). The manufacturer and country of manufacture are on the frame. Manufacturer and country are just 'nice to know' information. Any trace for lost, stolen, or criminal use will only need the serial number and maybe the model number (if the investigator is amazingly ignorant of firearm models).

The 'official name' of the two halves that screw together is the "frame and trigger group". (Then again the 'official name' of what we call the receiver is the "barrel support and optical sight group"). Being the only really metallic part of the PS90, I can see why the serial number etc. are where they are.

If I take a look at my S&W M&P the only thing on the receiver is the serial number plate, everything else is on the slide/dust cover/frame/call-it-what-you-will.

 

[SAVAGEJIM]

Same on mine. Only caliber, SN, and model appear as stamping on my receiver.
The country, city, state/province of manufacture is engraved on my polymer stock piece.

I believe that since (A), (B), (C), (D), and (E) do not have the specific stipulation of "must be placed in a manner not susceptible of being readily obliterated, altered, or removed," the requirements of (A) through (E) do not need to be permanently cast/engraved/stamped into the receiver.

No, neither "screwed up."

 

[Kramer]

Thanks for bringing up an issue that if true could have resulted in the confiscation of all PS90s.

And, please don't write a letter to the ATF to confirm, we have lost enough already from the "Letter writers".
