Once upon a time I purchased a 6904 from a member here but never carried it. I don't have any good reason other than I do not prefer 9mm.
For a few years I was carrying my Frankengun 4506 (lower) with a 4516 (upper). Technically that makes a 4596. I prefer .45 ACP and this combination gave me a 8+1 configuration. I still own it and it is probably the best-shooting .45 3rd Gen I own, although I no longer carry it.
For the past few years I have gone over to the CS45. I own two - a stainless CS45D and a blued CS45 - again both purchased from forum members. I have wood grips on both, which make them the most comfortable .45 CCW pistols to conceal that I own. Stock they are 6+1 and I could use a higher capacity magazine but I don't really feel the need. They also conceal VERY well, even for a larger guy like me.
