There is more after market support for the Gen2. That said as a basic "truck gun" and plinker the gun will serve you well. I have the Gen 2 now and it really doesn't shoot any better than the Gen 1. Both are a load of fun. For me the biggest downside to both Gens are the stock sights. I used a 13/64 drill bit to open up the peep sight on mine. After doing so the sight became, for me, more user friendly. I would be looking at a Beretta CX4 Storm or the Ruger PCC as options to consider. If all you are going to do is use the gun at your range the Retricted CX4 used are going for around $600 on the exchange which would be a less expensive and, in my view, a better option than the Gen1 Sub2K
