When are you going to start making the heavier and lighter exhaust valve springs for the 391 Beretta's? Cole has the market cornered on these.

Jim; I have found that buy going to the "blue"spring it allows more gas to escape slowing the bolt. For me it provided a significant reduction in how hard the bolt impacts the back of the reciever thus felt recoil. If you haven't tried one try it for yourself and see what you think. My 391 still cycles lt. 1oz loads no problem. I do pay a little more attention to how clean I keep my gun. I shoot registered Sporting(NSCA 535529) and have used this set-up for about 8 years now, no gun malfunction issues, I shoot slow reloads at sporting(1100 fps) but want to stay with 1 1/8 oz for the longer stuff we shoot there. The spring is just a couple thousanths small in dia. than the regular spring.Don't take my word for it. If you shoot a 391 try one and let me know what you think. I would think trapshooters would flock to this!
