My P239 in 9mm
I carried it for years with a 2nd mag in my pocket.
Great gun IMHO
You will love it. I one the way mine handles and carries.
As for a IWB I would look at a Milt Sparks VM-II. It is one of the best IWB holster there is. I have several VM-II's for the different weapons that I carry.
You can find them at www.topgunsupply.com
or on eBay. I even found them on www.gunbroker.com.
Good luck and hope to see your range reports soon.
