I've never had an FTF or FTE with 124 gr. Golder Sabers in any of my five CCW or HD 9mms. Based on all of the studies I've seen, including what MILSPEC FMJ did during my three trips to Iraq, it almost flat out doesn't matter beyond reliable function, penetration, and shot placement. The energy differences and permanent wound channel results are negligible. Frankly, I'm nearing the opinion that ball/FMJ might even be a better option (ok, so I'm a heretic...) since penetration is generally better (look at the FBI studies for my logic), and they generally are more effective when hitting bone. As far as the overpenetration-adverse, any shot with any firearm risks harm to whatever is beyond the target, so shooter awareness is the most important factor.Does the 124gr. Golden Sabers do well for defense? I've seen a few "back yard ballistics tests" that showed them as a less than perfect performer. It could just be those tests, though. How do they do in real world scenarios [if that data is even available]?
What I like about Golden Sabers is that they usually feed pretty well, due to their design.
