I've always thought that was just a silly Glock basher comment. Like the 1911 hasn't been updated/upgraded in it's production run, or even variations on the BHP for that matter (you know, internal vs external extractor). There are several variations on John "the gun god" Browning's Colt model M, so I guess he didn't get it right the first time on that one either. Or how about the very popular S&W model 686-5, yes dash 5. That means there was a 686 no dash then a dash 1, 2, 3, and 4 before it got to a dash 5.
Funny how the Glock bashers find it objectionable that Glock continually works to enhance their products, but tend to ignore it when other's do the same. Yeah, I find that odd.
