Your new S&W M1911a1 pistol looks like a nicely enhanced one.
Texture grips with front strap and back strap checkering.
Lightweight components. Front and rear slide grip serrations. External extractor.
Here's my Ruger SR1911c:
As you can see, no ambidextrous safety. No front strap checkering. Rear slide serrations only.
I do know that Ruger is manufacturing their own components for this gun, including the investment castings for frame and slide.
The finish quality of both guns looks similar. The fit of the Ruger is quite good, but not quite up to the Dan Wessons I have.
