I can’t seriously see what type of hand would fit the arched backstrap. It’s just plain uncomfortable. Every one I buy gets immediately changed over.Perhaps I don't have enough "nuance" to know the difference, but 1911s are the hand guns I shoot the most (by a large margin) and I cannot say that I have a definite preference.
I also cannot say I have shot them back-to-back for an "official" comparison. Hmmm????
I'll get back to you next week when weather and work let's me try that out a bit. Great thread!
