a good suppressor should last a life time. Make sure your company is reputable encase there is a problem that they can repair it. It may cost you an extra tax stamp but should not cost any thing from the factory.
Shot placement is everything! I would rather take a round of 50BMG to the foot than a 22short to the base of the skull.
all 26 of my guns are 45/70 govt, 357 mag, 22 or 12 ga... I believe in keeping it simple. Wish my wife did as well...
