I own three and have owned many over the years. My first being a high mileage RL1050.

I have broken a few parts over the years because I was a dumb-ass. All in all, nothing really wears out or is breakage prone.

For striker fired pistols or revolvers, you cant beat the way a 1050 seats primers. High primers are a thing of the past unless you screw up.

Old pic below, but now days the two on the left have bullet feeders.
