Yes, perfection at last! Sometimes the past holds the answers we seek...my new-to-me 2nd Gen 19. Made in 1995...grip feels better...looks cleaner without the rail...it's renewed my love of Glock! Ah, simplicity! How I wish Glock would offer all of their models for current sale, people would be so much happier. (Glock, are ya listening? Can you hear me now? It's a great idea!) I've read various answers, but does anyone definitively know what this means?
