M&P 40 Pro Barrel Life

[Parks]

I have been running an M&P Pro in 40 Minor for Production.

Was wondering if I can expect to get a longer barrel life running minor ammo at about 133 - 135 power factor.

Loads are 180gr platted @ about 750fps.

Have about 17,000 rounds through it. Still seems accurate. Actually have not replaced a thing on, including recoil spring.

I do take good care of it - clean and oil/grease about every 1,000 rounds.

Was also wondering if it is true that a barrel will loose velocity as it wears out reducing the power factor?

Appreciate any insight.

Thanks

I bet the lands are still sharp. In my experience with an M&P, there are parts that will wear out, but the barrel isn't one of them.
