I have been shooting the SX2 for about 5 years now. I was a dedicated pump gun shooter until I got the this gun. I use it for everything that has feathers. It has killed a bunch of turkeys and waterfowl. I have never had any problems with it not firing or jamming. I do keep it clean but then all autoloaders need to be cleaned regularly. I have the 3.5 inch version. It shoots everything yoiu feed it.
psychmonky is right about the shared parts. I have talked to reps from Browning and was told that internally the Browning Gold and the Super X2 are the same. The SX2 will run about $200.00 less that the Gold.
I love mine and would not shoot anything else!!
