Will be carrying a G20 after Christmas for self defense. I work alone in a high crime area so I am upgrading to the 10. I am not really interrested in mail order only ammo like BB or DT. I plan to get some for fun but for now need dependable factory ammo. I think the silvertip is slightly outdated, but you tell me. I need penetration, I work among lots of cover I may need to shoot through. I can live with a little overpenetration, its a pretty desolate area. I just need balls-out power any druggie can feel. Does any factory load come close to DT or BB on power? I will sacrifice a a little energy for total dependability. What do I need? Wanna kill these ads? We can help!
