G-27=Best carry gun ever. I could whittle his collection down to three frames but still have the same amount of options. If you buy the .40 S&W frame in any particular size (full, compact or sub-compact) you can buy the 9mm and .357 Sig barrels for that frame size and interchange them. Literally takes 30 seconds to change the barrel and mag out and go from shooting .40 S&W to 9mm
