Ordered for a spare as can never tell the way things are today as to determine when parts will be available in the future. Guess I am wondering when things will become scarce for the gun lovers in this country just trying to be prepared.

I tried this kit with a PSA Department of energy 7 and 1/2 in 9 mm pistol caliber carbine and it had absolutely no effect on reliability. It may have even made it worse. If you're using this for anything under 10-in Barrel you're wasting your time an...

Product Info for FM Products PCC 9mm Heavy Buffer 6.5 oz w/ .308 Carbine Recoil Spring

The Foxtrot Mike Products PCC 9mm Heavy Buffer combines a heavy buffer and a recoil spring in order to create one of the most reliable, durable pistol caliber carbines on the market. The 9mm buffer created by Foxtrot Mike Products is designed for all 9mm blow-back operated pistols. With a 6.4 ounce (pistol) weight, the Foxtrot Mike 9mm PCC Heavy Buffer has a 3.7 inch overall length and does not require a spacer or spacer remover. The addition of the extra-heavy duty .308 carbine recoil spring helps too, since it is critical to the feeding and reliability of a blowback operated pistol caliber. The extra-heavy duty recoil spring found in this buffer kit, is superior to any stock buffer, because it has a proper spring selected specifically for the blowback operation of a blow back pistol. With the extra-heavy spring, the FM Products 9mm buffer creates less felt recoil, is a simple installation, and you're good to go.image
