I finally bit the bullet.

For whatever reason, I just felt like I had
to have a stainless MarkIII. I ended up purchasing the same pistol
that I already have in a stainless version, the MarkIII model 10103.
So now I have both models in the target. After I made the purchase
and shot it this am, I was asking myself why?
There was a little difference in this model vs the model 10101 as
far as the pistol shooting wise. From day one I never had a jam
or misfeed in the 10101. I noticed the stainless version had some
little quirks which I kind of figured out what to do. One of the
guys at the range who apparently is the go to guy if you have
problems putting them back together said it was just new.
Funny thing was the gun shop (Styx River Shooting Range) told
me not to take it apart. They said if you do, you will end up
talking to the fellow who I mentioned was the go to guy.
I did meet another guy who also had a markIII and he took his
apart & showed me. I asked if he thought we could take my older
markIII apart, and he said the 1st time its so tight you probably
need a soft mallet. I asked him if he could pull the mainspring housing
out. He figured it probably would be to tight without tapping the
pin. He was right.
