Here's a tidbit of feedback:
A lot of your entries are "Glock 19 ..." but could equally apply to almost the entire Glock line. If you make your posts more general, you will potentially increase your appeal. For example, I don't own a Glock 19, but as a Gen 3 Glock 26 owner I found the articles about the sights, finish, and accessories interesting.
Had I not been to your website at your invitation, I might not have clicked on any of those stories simply because the title said "Top 10 Glock 19 Accessories" and I'd say to myself, "but I have a G26, so I don't need to read it."
Otherwise, nice blog.
