I have carried my gen 2 G23 duty Glock for pretty much everything since retiring from the SO, simply because it ALWAYS works, I live in Colorado and spend my time fishing , camping and a little hunting am thinking of a 10mm or 357sig Glock to replace my G23 , Need some input??? change, done change?? which cal if any???? thanks guys,almost forgot, the worst thing ill run into is a bear, and im guessing you will say the 10mm slug will be best for this? if so ill get a G20...THANKS GUYS AGAIN, I HAD NO IDEA NO ONE MADE A 10MM BBL FOR A g23....SOOOOOOO, ILL GET A G20 0R g29.....
