Nope. I rather carry steel and a little extra weight. Plus most plastic pistols have no saftey and no external hammer. . I much prefer a nice commander size 1911 45ACP for carry.
In all steel semi autos I have a CZ75BD, a CZ Rami 2075, a Smith 5906 and a Smith 4046.
As much as I love these guns I almost always carry a Smith Sigma 9ve. It holds 16 + 1, shoots very well after trigger work, is sized and shaped perfectly for concealed carry and is light weight. Much lighter than anything all steel. I've also got a Kahr CW9 for the times when I want deep cover.
I've got holsters for all of the all steel guns and do carry each of them occasionally but the weight can be a problem.
