This thread is intended to show photographic examples of frame generation comparisons, common-use Glock terminology, less-common variations, and other things that are helpful to folks who may have never heard of or seen certain Glock-related items. Below is a comparison photo of the various 9mm full-size frame generations with labels (right-click to open a larger, more detailed version in a new tab or window): NOTE: Images have recently been moved to a new host. If you begin reading/browsing through the thread, and see a bunch of "this image is not available" boxes, it is probable that I have exceeded the total bandwidth of the free account that is hosting the photos/images. If that is the case, please consider bookmarking the page and returning in the first week of the following month, after the account bandwidth is "re-set" to zero. Thanks, and hope you enjoy the info/photos/images!
