IMHO the is not a better 45 ACP pistol. I have used the 4566 for years. I have other 45 ACP handguns, and others, and there are many very good handguns, just as good. I have found that the 4566 has been 100% reliable for me, and I trust it more than a good 1911. My 4566 sleeps beside me, an travels with me often. A good choice.
