Like mine
I have shot both, and own a 2340.
Is the P-Series better, yes. Is it $150-200 better, Well that depends on how much money that is too you.
I am a poor man, and for What I paid for my Pro $480 w/night sites NIB, I don't feel that I coulf have got a better gun. I wanted a SIG, and this brought it into Range for me.
Thoughts
at first I was a little disapointed with the trigger pull, but after 500-600 rounds it has come around nicely. I like the gun a lot now and feel very confortable with it. It is way more accurate then me and is reliable, except with this cheap reloads that I bought at a gun show. All in all, its a plastic SIG. If you don't like Glocks, like me, then the only other options at that price seem to fade.
P.S. Before I get Flamed by the Glockephiles, let me just say that I have nothing against Glocks, I just don't like the way they shoot. If the SHTF and someone handed me a Glock, I would not complain.
