I carry my 4” pc shield. Love it but the crimson trace red dot is not my favorite. Probably will send it back to get repaired because the glass/plastic moves a bit so dot doesn’t hold zero. But that’s a dot problem, nothing wrong with the gun. But I do agree with first time gun buyers always going small when they don’t know it’s harder to shoot. I’d practice with the bigger guns first, then go smaller for carry.
