The steel framed Kahr is MUCH heavier, like 9 ozs, so it's for practice, not pocket carry.  The Rorbauch will never TOUCH the P3At's market.  The Keltec is $300, and 9 ozs, and the R9 is about 3x the price. Soon, used P3AT's will be readily findable for $200, while the R9 will probably never sell for less than $600.  So only the very serious ccw man will be getting the R9.
