Re: sig p238
I have a P238 and love it, it's my summer carry gun and I have roughly 900 rounds down the pipe without an issue. Mine has the hogue wrap around rubber grips and the extended mag. I don't think i'd like it as much without the extended mag as it allows me to get my whole hand on the gun. I only run FMJ ammo in mine for the little extra penetration, even in the summer.
The only sugestion I would have is stay away from the ones that don't have the 27A at the beginning of the serial number. IIRC they were the early models so you shouldn't have a problem there if your buying new.
I think you'd enjoy it if you like .380's, the thing absolutely fades away concieled and it's very accurate at self defence ranges for such a short barreled pistol, along with factory night sights, you can't go wrong.
