I'm getting my Hi Power ready to send off to Don Williams.
My main interest is to have a great trigger, so he is installing the Garthwaite parts and modifying the reset while eliminating the firing pin safety.
I have been agonizing over finish options.
I really like the look of the bright (NP3) slide, and the black frame (Roguard).
Is this going to cause a problem with glare?
He is going to install a set of Heinie sights with a fiber optic front.
To be totally honest, I don't really have the funds to do any custom work to stipple the top of the slide, so it is going to be left as a MKIII.

According to Robar, not a problem with glare.

"NP3® is a satin gray, non-reflective color ideal for all firearms."

I have a number of Sigs with bead blasted SS slides. The color is also satin gray in appearance. Zero issues with glare. A smooth bright finish like chrome or polished SS would have considerable glare in direct sunlight.

I have 2 SIGs with the 'Norton Special' NP3 treatment. There is NO problem with glare.

I just had my Colt 1911 Gold Cup frame finished with Roguard satin. I just did the frame because I love the polished blue on the slide.
The satin is shiny beautiful on a well polished part. So much so that the slide is going back (after I scratched in the range bag) to get it done with the same.

You're gonna love the way it looks.

Thanks for the help!

If this is your first work being done by Don Williams, I feel sure that you will be very pleased....plus he is a gentleman to boot.
