Thank you for the measurements!
I loosened the retention screw but the screw wasn't that tight to begin with. I lubed the inside of the holster and I can now insert and draw easier. However, it still rubs the slide enough to leave what appears to be material from the Kydex on the slide.
I'm not sure what they could do to correct it. I know they used the P227 Nitron as the mold, so I doubt it would make a difference if they made me a new one using a SAS G2 model. Since it's tight on the slide and not the frame. Tony is willing to tweak it but now I'm not sure it needs anything.
Check out the rub marks on the slide from the holster. What do you think? Normal or too tight? It seems to draw fine now.
Here's a comparison between my G17 holster and the P227 SAS holster.
