Made in the USA!

These screws are an easy and great way to update your Kel Tec. They are high quality and will outperform the original ones. I highly recommend.

Buy the pin and screw kit together

Screws are a sweet upgrade but don’t be cheap. Buy the pins and screws and pins together in the kit. You will want the pins, believe that!


Work great, already Rusting

I purchased the all in one trigger job bundle which came with the carbon steel screws and grip pins. However just a short 3 months after install I noticed rust beginning to build up on the screws. I live in the south in deep East Texas about 35 miles west of the louisiana border so rust is not something I'm unfamiliar with. However, the rest of the gun is doing just fine and I usually keep everything covered with a layer of lubricant as to fight off rust when not in my safe. I'm not sure if I should pop them out and hit them with some corrosion resistant paint or not.

Some what satisfied

I installed this simple upgrade so I wouldnt have to worry about striping screws. Unfortunately one of the screws (barrel hinge point) has a mis-shaped head and stripped out right away with very little torque applied. The rest of the screws were perfect. I believe I just received one bad one. Can expect them to check them all I guess.
