Rumors of a Gen 2 coming out to S&W product line are just rumors, no changes coming. Plus, S&W would not call it a Gen 2 version. S&W is working on getting a military contract and are doing some internal modifications to some of the guns that will be in the contract, should they get it, but not to the commercial version(s).
The guns that are new (already released to the market) are the following:
SW22 Victory (.22LR)
M&P 15-22 Sport (.22LR)
PC Ported M&P Shield (9mm & 40 S&W)
