I'd like to hear from some one that has actually used, or at least handled, a Glock with the Crimson Trace LG 417 and also a Glock with the Crimson Trace LG 619. Which one feels the best in your hand, and why? I'm thinking about ordering the 417. Is the 417 any thinner than the 619, and does it activate easily? Wanna kill these ads? We can help!
