Happy with purchase

Bought and installed all items per video. Everything worked as advertised. However, it would be a great addition to add a short clip of how to reinstall the sear if you accidentally take it out. ;)

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.


quick & easy

I ordered the trigger, guide rod, recoil spring & spring kit for the Keltec PF 9. good service & easy install with the You tube video from M carbo. 20 minutes to lock & load. I can feel the difference.


Now THIS should improve my accuracy

I just finished installing MCARBO's upgrades to my PF9: flat trigger, trigger spring kit, hammer spring, and 20-lb. recoil spring. Except for my forgetting to move the hammer block out of way (which prevents you from finishing reassembly), everything went smoothly. Vastly reduced trigger pull force and improved release. I have not yet shot the gun, but expect my grouping to tighten up a lot! One other note: Upon reinstalling my Crimson Trace, that device interfered with the trigger pull. Had to shave down the CT's plastic inside of the trigger guard slightly (with a utility knife) so that the trigger would clear it. No big deal.

Works great

It was easy to install. It made a big difference in trigger pull.
