My first one lasted two years, but Charlie said a small piece of rock'n'roll tape on the front wear point was add another couple years to the life of it.
Not for everyone's carry situation, but it's been perfect for mine.
i picked up a similar rig recently, it works great for small revolvers (i carry a sw 340pd in mine........only drawback is i drink a lot of water and i swear this thing is such a pain when its bathroom time, or am i doin it wrong.
