It has taken long enough, but finally the .40 S&W chambered version of the 9mm Ruger SR9 has arrived. Ruger has been shipping the SR40 to dealers during the past week. The one pictured below is being sold on GunBroker.
Ruger has kept silent about the SR40 and I do not know the official specs of MSRP. Dealers, feel free email me any info you have.
UPDATE: The MSRP is $515.99, the same as the SR-9. Many thanks to Brian for the info.
