Will it beat itself to death in normal use? Probably not.
And trust me, a tuned firearm is a pleasure to operate, whether you are competing with it or not.
But I say again, there is nothing like operating a rifle that has been properly tuned vs one right out of the box. It just feels nice
So, to reiterate,The Uberti was tuned by one of the top gunsmiths in the business. It operates like liquid gold.
no, you do not NEED an action job. Unless you WANT one.
I will add, that it doesn't hurt to smooth the innards of your rifle. I have done so on a few revolvers and a couple of rifles. There are different methods and tools to use. I always use a really fine grit sanding sponge from the auto section at Wal-Mart. It isn't hard to do, and for someone new to this type of firearm, it gives you knowledge about the inner workings of your rifle.
P.S. My stock, un-tuned Uberti 1873 rifle I bought from Dixie Gun Works takes one finger to work the lever and is quite smooth as it came from the factory.
