The SX3 is a really nice shotgun. It is fairly light, and soft shooting. Internally, it functions the exact same way and most internal parts relating to the gas system, if not all are exactly the same as the Silver Hunter. With the SX3 you get a lighter gun and you save yourself a bit of cash. I have used one, the store I work at has one as a demo between all of us its seen many cases of shells through it with zero issues. I'd guess at 2500+ shells fired at the very minimum. I can't comment on the Versa Max through using it, but I've handled one. It does feel nice in the hands but it is does feel significantly heavier than the SX3. We have sold dozens of SX3s without any complaints.
