I stopped by a LGS the other day, and was able to handle a USPf 45 and a 45 elite, and apparently they could get a 45 expert in easily enough. Not only do these fit my hand, they feel better than expected. And the elite balances surprisingly well.
Do I need one of these right now? No, not really. No plans to visit Alaska or the northern rockies in the immediate future, the only brown bears around here are on the state flag, and I have other HKs that are capable of handling what does occur locally. Still, it's tempting....
