Strengthen & Customize Your Polymer80 Build with the NQI Black Nitride 3 Pin 4140 Steel Set
The NQI Black Nitride 3 Pin Set is the ultimate upgrade for your Polymer80 PF940SC build. This kit is precision engineered from rugged 4140 steel, CNC machined for a perfect fit, and finished with a sleek black nitride coating for increased surface hardness, corrosion resistance, and a premium look.
Each set includes three critical components:
- A black dimpled trigger pin
- A raw stainless LBRS front pin
- A black trigger mechanism housing pin
These pins won’t bend, crack, or break under normal shooting conditions — unlike some standard pins that can wear out or even get lost during maintenance. They’re designed to drop into your Polymer80 build without interfering with holstering or presentation, ensuring smooth function and dependable reliability.
Whether replacing lost or damaged stock pins or upgrading for enhanced strength, this set is an essential addition for Polymer80 owners who demand long-lasting durability. Pair them with our custom 17-4 front and rear rails for a truly rock-solid platform.
