Has to be a Benelli M2 with all the toys and trimmings.
Although the Versamax is a carbon copy of the M2 (a bit of a shameless one at that)
But pull the bolt back on each one and you will immediately notice the difference. The VM is gritty and crunchy, forward heavy, and just felt abit off. I did notice some metal shavings in the receiver...
The Benelli by comparison is smooth, feels more like an extension of me and points very well. None of the above issues.
The biggest difference I find between Pump and Semi is pump is:
Semi:
quicker to target, less recoil but limited capacity
Pump:
Unlimited cap (YMMV) cycled by you but cycled by you, kicks abit harder, sometimes heavier (with a large mag tube)
If money no object, Benelli M2, price limits, Remmy VM.
