Northwood Trigger Installation Guide

Kel-Tec  P-32

NOTE:  The Northwood P-32 and P-3AT triggers have been discontinued.

The Northwood trigger compliments an already smooth internal action with the enhanced "higher end" feel of a metal trigger. No changes to the firing mechanism or pull weight are being made, as these settings have been carefully engineered by the factory. The Northwood design has a more comfortable saddled curve for larger fingers, provides slightly more room ahead of the trigger in the reset position, and has slightly less over-travel when firing. Although the stock polymer trigger is acceptable to most, a precision-shaped metal trigger has another feel entirely.

Kit Contents:
  • Northwood Trigger #NP323AT
  • Trigger Pin, Stainless 
  • Set Screw 6-32 x 3/16”, Stainless, Loctite-Coated
  • 2mm Pin Punch
  • 3mm Pin Punch
  • 1/16” Allen Wrench


Make sure your firearm is unloaded. Follow all safety guidelines in your owner’s manual when handling your firearm.

NOTE: This trigger was designed as a drop-in part. However, in some cases it may need further fitting for your firearm to function. The trigger surfaces or polymer grip may need to be filed or sanded to obtain the proper clearances required.

 Tools and Items Needed:

Standard gun cleaning materials and lubes

Small hammer

Gun mat or soft working surface

Small wooden blocks

Flat Blade Screwdriver, Long (narrow tip)

Needle nose pliers

Small Diagonal Cutters

Gallon-Size clear zip-lock bag

Unless the step is specific to the P-3AT, photo illustrations will be of a P-32.
Most procedures are identical. Model-specific steps will be noted.


IMPORTANT:   Inspect the gun carefully, while performing these steps, and replace any worn or cracked components before attempting this installation.

Start by field stripping the pistol. You are working primarily with the grip/frame assembly. Once the slide assembly and magazine are set aside, begin with the frame removal.

Support the pistol on its side between two blocks of wood, books, a cartridge rack, or some other appropriate spacer. Using the 3mm punch and small hammer, tap out the two frame pins, as shown. Tap from the smaller end of the pin toward the larger end.

NOTE: If these plastic pins were replaced with two-piece metal machine screws for mounting a belt clip, simply remove the screws (and belt clip) using the appropriate tools.

For P-3AT: Remove the ejector from the frame as shown, and set it aside.

With the pistol in one hand, hold rearward pressure on the hammer with your finger while slowly pulling the trigger. Once hammer is released, allow it to rotate fully forward.

Insert a long, flat bladed screwdriver (medium tip) through the frame and grip, and under the hammer spring retainer next to the spring.

Push up slightly on the spring retainer until it clears the recess, and move it toward the magazine well.

Twist slightly, and let the spring retainer down into the magazine well.

Using the slide as a lever, begin lifting the front of the frame out of the grip until the trigger components are partially visible on the sides of the frame. Do not lift the frame out of the grip just yet.

Remove the slide from the top of the frame, and set aside.

CAREFUL! There are parts on both sides of the frame that will fly away unless you hold your fingers along the sides as you pull upward.

IDEA: Remove the frame with both hands inside a gallon size zip-lock bag to catch parts if they come loose.

As you pull the frame clear from the grip, the hammer spring and retainer will come with it, and will dangle from the frame. Leave them attached for now. Keep holding the left and right frame components to the frame as you remove it from the grip. The trigger bar on the right side is spring loaded.

While holding the trigger bar on the right side, turn the frame over. The left side components are the slide stop lever and spring.

For P3AT:
There is no slide stop lever - just the
assembly pin spring. Remove the spring and skip down 2 steps to Trigger Bar Removal.

The P-32 spring sits on a nub in a circular cutout with the lower end riding in a very thin slot on top of the slide stop lever.

While still holding pressure on the right side (trigger bar), carefully release the slide stop lever and spring – and lift them away from the frame.

Set the slide stop lever and spring aside for now.

Trigger Bar Removal:

Turn the frame assembly back over to the right side.

Note the trigger spring “tab” is positioned in the trigger bar slot. While holding down the front end of the trigger bar (shown below), carefully lift the larger end slightly, away from the hammer axis (pin).

Rotate the trigger bar clockwise, allowing the trigger spring to unwind out of the slot in the bottom of the trigger bar.

The trigger spring will not fly away, but it may sting your finger if it slips out of its groove prematurely.

Set the trigger bar aside.

Trigger Removal

First try to remove pin with a small screwdriver or needle-nose pliers. If it won’t come out gracefully, you will need to snip it out.

Using a small diagonal cutter or similar tool, snip away the bottom part of the plastic trigger from around the pin.

Pry the trigger pin up from the trigger slightly to release the spring loop.

Then grab the head of the pin with a pair of pliers, gave the pin a slight twist and pull it out.

Remove the trigger spring from the right side of the trigger axis, and set aside.

Gently push or tap out the trigger axis from the left side of the frame with the punch, and set aside.

The top of the plastic trigger can then be removed from the frame.

Finish cleaning any remaining oil or grease from the frame and trigger cutout area.
