Bought my Sig P239 in 40S&W a long time ago. Used it qualify for my CCW classes and when it came time for renewals it came through with flying colors. Since mine only came with two mags decided a few extra wouldn't hurt. When asked how many mags I wanted I told them 4 and out comes the clerk with 4 brand new P239 40 S&W mags. $45 bucks a pop still took all 4. The leather mag holsters for the P6 will easily hold the P239 magazines. Seems I went kinda crazy when the P6 came out. Extra magazines, about 3-4 different types of holsters, and of course the holsters. Love my P6 as it's just the right size for me. I could have had a Swiss Sig pistol cannot remember the model except it was in357 Sig and didn't want another cartridge to reload for. Not one of my more better moves. Frank
