For about two years my local rifle gear was out of stock for this model. Needless to say I bought one of these asap when it was back in stock. The Mossberg 590A1 with a 20" Barrel is an impressive piece of machinery. The fit and finish is immaculate and the magpul furniture really ties this gun together. I really like the intuitive design of the tang safety. No cross bar trigger lock to fiddle with, just a straight forward and back action with your thumb. Easy, safe, and fast! This being my first shotgun I am very pleased I went with Mossberg, especially this model, over the Remington model 870.
