I've gone to the range 3 times in the past week and have done almost a 1000 rounds through 4 guns. In between those sessions I have been doing a lot of reading and research.
The biggest thing for me right now is learning to shoot properly. I have a lot of work ahead, but I do enjoy the challenge.
I shot the Berretta 92FS, the Sig P226, the Glock 17 and the S&W M&P9
The Sig was by far my favorite followed closely by the Berretta. I also shot the best with those two. But at this point I think it is just beginners luck. I tried the S&W because I have heard the grip feels a bit like a Sig and the price is a bit more affordable.
I did not like the Glock or the S&W as much. They felt almost too light. I liked the heavier guns because when I fired they felt much more balanced. Again I still have a lot to learn.
There is a Sig Sauer Academy up here in NH. I plan on doing a weekend long pistol course at the end of the month.
