I would say they should last a long time if you don't try to make a range gun out of one. Firing a couple hundred rounds through it evey time you go to the range. I shot a couple of boxes through mine to get to know it and break it in. Now I just shoot a couple of mags through it about every other time I go to the range. After all these guns were made with the idea of up close and personal. They are a great back up gun. I think they will last many years.
