One of the guns I have my eye on is a Sig, either a 229 or 239. While there are small differences in barrel length, etc., when I overlay them, they seem virtually identical in footprint.
The primary difference is the width. The 229 is 1.5" wide, while the 239 is 1.2". This is because the 229 has a staggered magazine instead of the single stack.
I like both, and in the absence of any other difference would probably get the 229, but wonder about the width difference for carrying IWB. It's in the grip rather than the slide, and therefore above the belt.
For anyone who has carried both, or similar guns, has that grip width made any difference to you?
