I think the best is a sig mosquito, it is very accurate and it is very reliable as far as not jamming.:
There are just so many different ideas of which pistiol is the best....I suggest you decide on something you like and then pose the question...."Is this any good? Everyone has a different opinion and all may be great pistols.
I've been having huge fun with my GSG-1911. I've got a quite a few bulk boxes of Federal through it without any significant issues. A fellow INGO poster has over 7000 rounds and counting. Only problem is it that it is horribly addictive to shoot. 500 rounds a week has proven very easy to do.
