If you are worried about trying to simulate "catching the link" during dry practice, you're screwing yourself. BANG-CLICK is something I wish I could purge instantly from my students, but instead I need to rely upon 3,000 to 5,000 repetitions. Such is life. If you've been trained to "catch the link" (press the trigger, hold it to the rear, gun cycles, sights back on target, let the trigger out to reset point, press the trigger again) you've been taught a technique that isn't particularly helpful. You're far better off simply relaxing your trigger finger during the recoil of the gun and being ready to fire that next shot when the sights fall back down on target. So with all that said, quit trying to simulate catching the link during dry practice. It's not doing anything useful.
