I had a sweaty/dirty day outside mowing/trimming and the new P01 got dust, grass, dog slobbers and my sweat on it, so I decided to clean it after I came inside and got my shower out of the way.
While tearing down the P01 I figured I might as well do the same for the every day carry P07 (had been meaning to do that for a couple days anyway).
The P01 only has about 60 rounds through it now. The P07 had something over 500 rounds through it (I don't count or keep a record but I reload and keep a log book for that).
The P01 has considerably more wear on the outside of the chamber and the barrel up near the muzzle where it rubs the slide. The rails on the frame don't have any finish on them, but a lot of that was missing when it was brand new.
The P07 only has a small line across the top of the chamber where the original finish is gone and while appearing thin on the barrel it has not worn through and gotten shiny up near the muzzle.
To look at them you'd think the P01 had been fired much more than the P07, much more.
The only reason (popped into my head while wiping/cleaning/lubing) I could think of was the P07/P09 designs being newer and maybe the machinery they are made on being newer, the precision of the parts in both finished state and fit to the other parts of the pistol is much higher for the P07/P09 guns leading to less wear/tear when the parts are moving around on each other.
Most folks seem to believe that the P07/P09 guns, in stock/production form, are more accurate than the older guns (stock - not loaded up with new precision/match parts and worked over by a gunsmith). That, too, could be a sign of the precision the guns are made with.
Just thought it was odd the P01 was showing wear in the finish so much quicker than the P07 (that P07 is over 2 years old now) and the P01 is about a month old.
