Kahr Polymer Frame Disassembly (Tutorial)

[AEnemaBay]

I noticed that there weren't any guides to disassembling the Kahr polymer frame (or I just have weak Google-fu), so I figured I'd give it a shot. This guide should be good for all TP, P, CW, and PM series of Kahr pistols. The pistol used was my new Kahr PM9.

DISCLAIMER: I AM NOT RESPONSIBLE IF YOU DAMAGE YOUR PISTOL WHILE PERFORMING DISASSEMBLY OR ANY OTHER TYPE OF MODIFICATIONS.

PLEASE REFER TO THE EXPLODED DIAGRAM PROVIDED BY KAHR ARMS ON THEIR WEBSITE:

2. T6 screw driver
3. 1/8” pin punch
4. Brass hammer (or other non-marring hammer)

Disassembly
1. Ensure that the magazine is removed from your pistol and that the chamber is empty.

6. Using a 1/8” punch, remove the headed trigger pivot pin (12) from the frame taking care to remove it from left to right. NOTE: TRIGGER SPRING IS UNDER TENSION
7. With the trigger pivot pin (12) removed the trigger (9), trigger spring (10), trigger spacer (11), and trigger bar (13) can be removed from the frame.

10. Using a dental pick, hook the magazine catch spring (18) and pull it to the side and outward in order to release it from the magazine catch (17).
11. Using a pair of pliers grab the top of the magazine catch spring (18) and pull it straight and out of the frame.
12. Remove the magazine catch (17) from the right side of the frame.

Reassembly Tips
1. The legs of the cocking cam spring (16) correspond to the holes in both the ejector (31) and the cocking cam (15) itself. The spring can be placed in either way and the entire unit in reinstalled into the frame.

2. The trigger assembly is to be assembled as shown below (trigger spring (10) has been omitted from the photo for clarity).

3. The easiest way to reinstall the trigger bar spring (14) is to attach the hook onto the bar as normal and then use a pair of needle nose pliers to grab the loop in the spring and then bend the lower half into the slot in the frame.

4. Do not, I repeat, DO NOT over tighten the Torx screws when reinstalling them into the frame. You are mating steel threads with polymer threads and if you tighten them too much the steel threads will win and gut the polymer. Only tighten the screws until they are snug!

If anyone has any other questions you can ask them here and I'll try my best to explain it and/or provide a more detail photo of the piece/process.
