There’s not a whole lot of info about SwissBianco recoil buffers in this video. You might even say none; I couldn’t possibly comment. The U.S. immigrant’s website is only slightly more illuminating. [Hint: cycle through the photo album.] For that we turn to Brownell’s website where the product description specialists deliver the goods (so to speak): “Polyurethane buffer cushions the impact of the slide against the frame during recoil, resulting in less wear to the gun, less fatigue on the hand and arm, and less muzzle rise. Reduces felt recoil so you can get back on target quickly for faster, more accurate follow-up shots. Each buffer is precision CNC cut from a sheet of ultra-tough, tear-resistant polyurethane. Drop-in installation without any permanent alteration to the firearm. Models available to fit Beretta 92 and Glock pistols.” We’re in. Report to follow.
