Let's just bear in mind that this is a sample of one, and all that. I have high hopes for the 2.0, but even if the other one I have available shoots well, it is too small a sample to say anything meaningful.
I have way more time on a G17 than a 2.0, so I don't think it is much of an honest comparison. Overall, I would say it is a better version of a G34 (closer in slide length). Better in that it cycles more crisply, where I always find the 34/35 to be a little sluggish for me. So far, I prefer the slide release of the G17. I think I would like to try an extended slide release on the 2.0, much like the Glock competition release.
I'm very unlikely to shoot either 2.0 much more than I did today, so I will probably not become more familiar or comfortable with them as a whole.
The Performance center version, with the RMR, turned in the fastest 10 yard plate rack time I've ever shot. Also the fastest bill drill. Pretty nice setup.
