All of the above, of course.
I use 1911, Third-Generation S&W, and Seecamp pistols with hammers. I use revolving pistols with hammers*.
I use Glocks, with strikers.
I Don’t Care what anyone thinks about my choices.
*Edited to add: “Hammerless” revolving pistols actually do have hammers. Look at the parts diagrams. (Perhaps, there are some few very rare, esoteric exceptions, somewhere, back there, in history.)
