If you compare the slide movement of one that had its slide "lapped" versus one that hasn't, you will feel the difference is movement.

The 1911 runs smoother with lapped slides.

Lapping is a machining operation, in which two surfaces are rubbed together with an abrasive compound between them, by hand movement or by way of a machine to remove machining irregularities, and to reduce friction between the parts.

Lapping can be done a single part to smooth a particular surface or, it can be done to mate and smooth two parts to each other. Engine valves to cylinder head or firearms slide to frame are common examples. The parts are usually slightly oversized and the lapping removes minuscule amounts of metal in a controlled means to achieve a tight fit with a polished and smooth operation of the parts.

As a retired engineer I will share with you my well/over used mantra; "Never change a running assembly." What's to gain? You will need to run your scheduled PMs which should include lube and visual inspections. Only make changes when indicated.
