I’ve heard multiple people swear by the M&P Shield. I haven’t fired one yet but plan on rectifying that soon.
At this point in history, I think most any of the modern striker-fired polymer-framed pistols from the leading manufacturers are serviceable, accurate and reliable — either right out of the box or can be made so without too much work or fuss.
Personally, I prefer double-stack Glocks for mag & holster interchangeability, but opinions do vary for different (quite valid) needs and uses.
