Overall Customer Rating of 33 Reviews:


For the price it was worth a shot, but makes for little difference in felt recoil. Perhaps a little less muzzle flip. Honestly just makes it harder to rack and reassemble.

KEL-TEC PF-9 parts

I ordered the following parts for the PF-9 on April 29:
20 pound recoil spring
Trigger spring kit
Flat trigger
SS guide rod
Textured grips
Bench block
Due to unavailability of parts, these parts didn't arrive until Jun 13.
All of the parts were installed at one sitting as I didn't want to disassemble the gun more than one time. Following the videos on the MCARBO website, the parts were installed without any problems and the changes in the gun's operation were very noticeable and made the PF-9 much more enjoyable to shoot. The process was easy and enjoyable, but patience and a little mechanical skill are required as some of the parts are very small and reassembly does take a little dexterity and finesse. However, the parts are well made, fit like a glove, and are well worth the time and expense to install on your PF-9. They will definitely improve the weapon.

Good springs

Springs way better than factory.. easy to install noticeable improvement.

works great

Smooth action

I recently installed the stainless steel guide rod and heavy recoil spring on my PF9. I assumed the slide would feel heavier, but I found that the slide was actually easier to manipulate. It felt much smoother than before. Highly recommend this upgrade. I haven’t had a chance to fire the gun yet but I will update when I do.
