Well,
I had an incredible range day today.
All I can say is SWEEEEEEET!

Took the "CS-10" and and "1013" to my LGS, they have a 7 port - 75 foot indoor range.
A good friend of mine works there.
I was surprised to see the range was empty on a Sunday.
Grabbed a box of 10 m.m. Federal 135 gr. BallistiClean Copper Bonded Flat Point ammo off of the shelf
and also had a 100 rd. box of my reloaded 180 gr. ammo with me and put it all through both firearms.

Also put the ambidextrous safety on it that I swapped from my CS-45, it makes racking the slide easier on your fingers.
I started off with the heaviest spring that I had made to fit.

The CS-40/10 recoil was quite comfortable with the Hogue grips and the thinned down Buffer Technologies buffer in it.

First shot was with just one round chambered with an empty magazine to see if it would lock back, it did and did not throw the brass all that far.
Everything cycled perfectly and the accuracy was as good as the 4013/1013 at 50 ft., I'm very happy/pleased.

This target is the first target of the 4013/1013 taken mid-May just to show those that have not seen it.
Today's were the same, the CS-10 printed about 1.50" low at 50 ft.
Just the opposite of the target shown.
I expected that being a substantially hotter round.
I don't have the targets from today, I forgot them at the range, sorry.

Now to go work on a Delrin grips to replace the Hogue's.................

Regards,
BM1
