Just wondering if anyone has had any experience with this round? Is it a good loading/choice for defense? It would be even better if that experience was with a Glock21. (Feeding/cycling) I took a leap of faith and bought 200 rounds of it at my LGS, never even seen it on the shelves in there before. I have some Remington Golden Sabers and Hornady XTP's. (Which I know are good rounds) just curious about this one in particular. Thanks for the info!
