P239 easier to carry and conceal
I have both the P229 in .40 and the P239 in 9mm. There is a noticeable size difference, as the P229 weighs 32 ounces empty while the P239 weighs 27.5 ounces empty. The grip on the P229 is also wider and longer, as it is a double stack gun with a high capacity magazine. I prefer to carry the smaller P239 because it conceals very well. Both guns shoot well and are accurate and reliable.
