Like a lot of you, when I graduated from the Academy in 1981, we had 1 choice, a Mdl 10 with 125 gr +P hollowpoints. Carried that(usually with a 60 as a BUG) till we switched to the 5606/6906 in 92 or so. I was a proponent of the 4506 but was informed it was "too much gun". Still have my 10, the 5606 and 6906 as well as a 5903 with Bomars and a trigger job from my PPC days. Used both the 10 and the 5906 for SWAT, K9 and range duties for 28 years before I hung it up.

As soon as I saw one, I purchased a 4506, and like a few of you said it feeds and shoots everything! It ran much better, and shot better than the 1911s I had prior to that, and even the one I traded for it. So does the 4566 that joined it when I got back from the sandbox! About 3 years ago I got a 4516-1 and so far it has been as reliable as it's bigger brothers, running everything from FMJ to HSTs and lead target loads. While I will probably always be a Kframe guy, the 3rd Gens are neck and neck for popularity with me.
