Para Ordinance makes fine pistols. I have had one of their P14-45s for about 13 years and it has worn very well after thousands and thousands of rounds.

As for the single stack, double stack debate, that is really up to you. Each version has their proponents. The single stack has a slightly thinner grip profile, but the double stack is not too much by any means.

I have medium sized hands and my double stack P14 fits perfectly.
