Introducing the Power House Valve

This valve is designed to work with higher caliber rifles. I have gotten 700ps with a 232 gr .357 Caliber bullet on a 26" barrel.  On the 29.5" barrel it will get 725fps that is 270ft-lb of energy. This valve has been place in 22 to 45 caliber guns with great results. I have built a 22 that shoots a 15+gr pellet at 1177fps to the a 45cal that shoots a 300gr at 750fpm. This is one very versatile valve.

Introducing Stainless Steel Triggers with Reduced Friction Device

Triggers have a wide finger pad for better feel than the factory blade and a bearing at the sear contact point to reduce friction.  The trigger fits 2240, 2250 and 1377 grip frames.  The triggers are made using CNC machinery to hold exact tolerances.  Of course, being stainless steel, it will never rust or stain.
