I own the Glock 19 and sometimes shoot a Sig p239. I've been shooting Winchester 115 and 147 grain range ammo and now i'm looking for a defensive round. I've narrowed my search down to the Winchester 115 Silver-tip or the Speer 115 Gold Dot. I found these rounds after looking for standard pressure rounds that had no chance of overpenetrating but hit with alot of energy to open the hollow point shortly after the initial penetration. The Silver-tip seems to have aquired a bad reputation for underpenetration however it looks great on paper with a velocity of 1225 and an energy rating of 383. The Gold Dot looks less impressive on paper: velocity 1200, energy 368, but these lesser ratings might cause it to avoid underpenetration. Well those are my thoughts, does anyone have any experiance with either round?
