Another observation on the size; since the gun is overall close to the Glock 19.
It would have been interesting to see what happened had Ruger built this gun to work with Glock 19 mags and Glock sight cuts. This would have opened the gun up immediately to the aftermarket given that it appears to already fit in some Glock holsters. Ruger could have shipped two Magpul mags with it.
On the other hand this would have cut into Ruger's magazine sales but I doubt most people buying the S9 would be buying a ton of mags. They could have raised the price $20 to offset the loss of sales and probably have made more money in the long run.
