From Down Range Firearms Training as they try the Caracal.
From Firearms Guide on the new Gen 4 Glock 21 in .45 ACP.
From GunWebsites on the new Springfield XDs45 Compact which is a single stack .45 ACP.
And another on the same XDs45 from Two Brothers Adventures which gives some more info on the pistol.
And finally, Colt's Bulldog Gatling Gun courtesy of NRA News.
UDPATE: One more to add. Caleb of Gun Nuts Media trys out the Springfield XDs45. I think this may be one of the hits of this year's SHOT Show.
