It is OK to be in any of the above groups and you're even allowed to be in more than one group!
That statement sums up my experience.
I bought a Glock 19 when they first came out. I never could shoot it well, but I admired the design and it's simplicity. My friends shot it well, so it was me and not the gun. I kept it for a couple decades, but a friend had to have it, so I sold it to him.
Then many years later I bought a Glock 27. This one is a shooter for me. It really surprised me how well and consistently I shoot it, especially with the tiny grip. So it became one of the few Tupperware guns that I have kept.
I have been eyeballing these micro 9mm's. They seem to be popular these days.
CDNN had the little Taurus G something 9mm micro on sale a few weeks ago for $200 and I was sorely tempted to give it a try at that price point. My gunsmith has carried one of the Taurus micro 9mm's for many years and I respect his positive experience and opinion of them.
But truth be told, the S&W Shield in 40 S&W or 45 acp would probably be a better fit for me. I found a Shield in 40 S&W at a pawn shop a couple months ago for $265 - which struck me as a decent deal. But I keep coming to the realization that I would be more likely (and happier) to carry one of my J-frames or Ruger LCR's than one of these micro 9mm's.
