Lots of people make their R9 "bigger" by using a grip extension to make the gun easier to hold on to. I'd like to have the slightly longer grip and get an extra round in the bargain.
Rohrbaugh could (should they wish) make both a 6+1 and 7+1 model. I expect the engineering on this change would be relatively simple.
I'd buy one in a heartbeat...
Well then, let me play devil's advocate...
Let's design it.
Since the grip is slanted, adding a round would make the R9 a smidgeon longer. So let's make it 5.8" inches long instead of the current 5.2" long. (You get that, right?... adding a round to the slanted grip would extend the grip further back as well as down).
Let's keep the R9/7+1 at .812" thick at the slide. No reason for a dimensional change there.
But for height, we need to add quite a bit for the extra round and spring to accommodate it with follower, so I think we're looking at a new height of the "High Cap"

R9 of maybe 4.3" instead of the current 3.7".
Lastly, we're going to have to have a heavier pistol due to the extended frame and magazine, so adding an arbitrary couple of oz. or so is probably about right. So now we have a "High Cap" R9 that weighs 16 oz. instead of the original 13.5 oz.
To recap, our new High Capacity R9 is now 5.8" long, same thickness, 4.3" in height, and 16 oz. inweight.
I wish to announce that you can, right now, today, buy your brand new "R9", and just for you, and if you act at your own leisure whenever you get around to it, you can buy it at about a third of the cost of the original R9.
This new High Capacity R9 7+1 pistol has a new model name. It's called a "Ruger LC9".
I'm liking it.
