NRA Show 2012: Introducing the Mossberg JM Pro-Series Shotgun Iain Harrison April 16th, 2012 | More From Iain Harrison Share0 Tweet Email Share on Facebook.Share on Twitter.Share on Google+While perusing through the various booths at the 2012 NRA Show in St. Louis, I was able to get a look at the brand new Mossberg JM Pro-Series shotgun. This shotgun is right up my alley — it’s made especially for 3-gun, and Mossberg partnered with one of the best in the business, Jerry Miculek, who uses this gun in competition. The JM Pro-Series features an expanded bolt release, a chamfered loading area and a variety of Nordic Components parts. Available with a 24-inch non-ported barrel for the 10-shot and a 22-inch barrel for the nine-shot, this well-received, gas-operated shotgun retails around $800.
