I used to carry my Sig 220 and Glock 27 on the job.
Now that I am an old retired fellow and don't go looking for trouble, I carry old guns that I like.
I like this .32 -
And I like this .38 and this 9mm -
And sometimes I like this .45 -
And sometimes I don't carry anything at all.
Just depends on how I feel on any given day.
