I emailed VZ Saturday about my R9 having a problem with trigger reset due to the spring under the right grip not being sufficiently held down by the grip (there is a suggestion that the use of tiny O-rings to hold the grip screws contributed in my case, but clearly not in many other users on the forum). Early this a.m. John VanZyck of VZ emailed back and is having a new set sent to me with an envelope to return the old. I would frankly have been happy to modify the grips myself if necessary because they add so much to the form and function of the pistol, but the superb customer service from John's company is really impressive. Gotta love gun people...they want to get it right no matter what...a good trait when a life may depend on the item working flawlessly.
