Hey Ron,
Great minds think alike. Picked up a 239 in .40 S&W Friday on the way to the OBX. Just got in and put it through a few mags in the back field. I LOVE IT! Much better than the 709slim it is replacing.
The paddle holster it comes with is OK, but sits a bit proud for CC. I found the Size 15 Uncle Mike's IWB (in either left or right) is a perfect fit, and I already had it from that POS Taurus purchase.
I love the night sights! This thing is just awesome. Finally retired the 92FS to the safe. Never was confident enough in the 709 to do that.
Do you know if the .40 is reverse compatible with .357?
If so, game on
