Help Which pistol to use ?

[kerokingkong]

I have 3 options; 1) 9mm Croatian Glock 19, 2) Sig Sauer P229 9mm, 3) Smith&Wesson Model 637 .38. Which one should i use ? the SW is a pretty tiny pistol however .38 seems more reliable. Also is it possible to trigger two pistols at the same time in order to CTB. I am considering using Glock aimed at Medulla Oblongata and Sig Sauer aimed at my left temple. I do not live in a country with relatively easy access for firearms so these are my only options.
