Thanks for all the info and suggestions, guys, but my old computer just may have made the decision for me over the weekend. It crashed and burned and I got pizzed and bought a new box, so I do not have as much in discretionary funds as I did when I originally posted.
I don't have a problem with telling you this will be in South Africa, but in some of the relatively better areas of Cape Town...a beautiful city. The seasons are reversed, so it will be high summer there. The G19 is a bit harder for me to hide in an IWB than a slimmer handgun would be, but I trust it, and if I shoot some thug it might be tied up in evidence forever, or handed back to me the same day...you never know over there. To me, a Glock is just a tool, with little to no "soul"...I can always get another. An excellent and reliable tool, but not like one of my old friends, my 1911's.
I will carry WW 127+P+ SXT and will have three mags at my disposal, although I may only carry one spare, depending on the place / situation. In SA if you have permission to carry, you MUST carry, or the weapon must be under lock and key. If it is stolen you may be arrested...and you do NOT want to see the inside of their jails!
As darm has noted in a different thread here, the "dynamics" of confrontation there are totally different than here, and while some victims are allowed to go unharmed or at least not deliberately killed, a great many are not, especially females, and I will be with an old and very good friend who is definitely female.
I will not "go gently into that good night", nor allow her to do so.
Still, my curiosity is up and I will be at the next fun show to look closely at the 239 DAKs..it is still possible I may try one out if it is noticeably slimmer to me.
