Great if your going for a mil-sim look. very accurate. good weight to it.
Weaknesses:
If you like to have a light gun it is probably not for you
Review:
I got my 1913 about a month ago and it has worked great. Compared to my proto barrel, it is just as accurate, and looks way cooler. It is definately a mil-sim barrel though, so if your not into that, I would not sugest it. But overall i would have to say this is the best barrel I have ever used.
Conclusion:
If you like mil-sim, the 1913 is definatley theway to go.
