I live in Costa Rica part of the year. This weekend I finished my 2nd seminar in AMOK!, a knife fighting discipline. It is not that I plan to become a knife fighter. I want to know how to defend against it and also how to get me blade into play. My friends in Costa Rica think I'm paranoid. I'm the only one of them who has not been robbed or mugged.
Ferfal, I have a question. CR is an NPE for me as a tourist. As such I carry only a Glock 19, no holster...a "clip-on') with just that magazine (loaded with DPX) so I can toss the gun if I need to do it. I prefer the 9mm and a few additional rounds to the 357 SIG. What made you decide on the 357?
9mm or bigger LOADED WITH PREMIUM JHP AMMO, will do the job, some will do it a bit better than others, but just a bit.
I have no problems with my Bersa 9mm as a self defense weapon. I keep it loaded with Gold Dot +P.
The 357 SIG gives you some more stopping power and penetration.
In case all I get is one, not so well placed shot, I prefer a 357 SIG shot.
Other like 45 ACP, 40 S&W or 9mm. They are all good as long as you use good ammo.
If you can only get FMJ, definitely go for “big and slow” (45 ACP).
As long as I can choose, I prefer the very fast, violent expansion of a 124 GR JHP traveling at over 1400 fps.
