If you get it for a good price, buy it. In today's climate you can always get your money back if you don't care for it. They are good, practical tools.

A few years ago, when I was still teaching the NRA personal protection courses, I bought a G19 just to develop enough expertise to teach effectively. Everybody had one, everybody recommended one, everybody wanted one. Mine was OK. Never had a malfunction. Meh.

Glock high reliability is touted everywhere. That said, I have not experienced a weapon induced malfunction in my home-built Colt Essex in years (32,000+ rounds later and lots of learning curve there). I have never had a malfunction in 3 Kimber 1911s, my SIG P229, or my CZ75.
