I believe (IIRC) it's a NP = Nelson Patriot. Again if memory serves (I've had a couple of concussions in the last month or so) the original NP did not have paddle that went behind the belt to keep the holster from "bowing" out as opposed to the NP-1 that did. TK is Tony Kanaley who worked for Milt and was the second person to own the company.

 

There were two Nelson Patriot models, the NP-1 and NP-2. I do not remember the differences. I think the NP-2 was a "bikini" type holster with an open bottom.

Here is the thread where the NP-1 and NP-2 were announced. https://www.1911forum.com/threads/milt-sparks-np-1-sneak-preview.2008/#replies

I thought the NP-1 had the paddle and came before the IQM, so my guess is the OP's holster is an IQM. This is from a review of the IQM, which was replaced by the Axiom.

I like the reinforced mouth and the semi "speed cut". The double snap loops are pretty cool. They seem to spread the weight of the gun over a wider area of the belt. The belt size adjustment allowance in the loops makes it convenient for folks who wear belts with different widths. I really didn't care for the "tongue" or "paddle" on the NP-1 (discontinued), I thought it added unnecessary thickness to the rig when worn, it's good to see Tony leave the paddle off. The double loops appeared to be "flatter" than the one on the NP-1.​

I believe farscott nailed it. I couldn't get the IQM to load in my brain. 😂 I owned at least one. The Patriot's were the NP-1 & NP-2...not as I had thought.

 

thank you both! I got it used a long time ago, just wasn't sure what it is
