Left to right: 1) 1986 to 1987; 2) 1988; 3) 1988 to 1989; 4) 1989 to 1990; 5) 1990 to 1992; 6) 1993 to 1994; 7) 1994 to ?
The above are approximations based on the following, please feel free to contribute and correct!
1) I think this is one of the earliest if not the earliest Glock brochure in the U.S. There is a second version that I believe is later from 1987 because it lists the American Firearms Industry award from 1987 on the top/inside - see my comparison photo below in unfortunately poor quality done using my iphone. I found another of these brochures that is on its wayI’m hoping it’s the second (or a possible third) version that I’ll compare further.
2 & 3) I approximate #2 is almost certainly from 1988 because it depicts a gen 2 G19 alongside a gen 1 G17 and G17L on the front cover. #3 depicts all three models as gen 2’s with no further models listed, so I approximate 1988-1989 as its year.
4 & 5) I am quite certain #4 is from 1989 through early/mid-1990 since it depicts the G20 with an “Available in Spring 1990” notation. This is absent in #5, which renders #5 at earliest from 1990. #5 I’ve found far more common than it’s predecessors, which I think is attributable to Glocks having become more widespread by the early 1990’s but also because that brochure seemed to have been used for a more extended period given the accompanying materials I have found with said brochures such as retail price lists.
6 & 7) Similar to the above, #6 can be dated to 1993-1994 since it came after #5 which I believe was issued well into the 1990’s, and furthermore lists the G24 as intended to be introduced in 1994 (see photo below). This notice is removed in #7 where the G24 is simply listed, amongst other changes such as a new photo on the inside front page.
