Is there a pattern to Glock's model numbering system? To me, it is very confusing.
The 17, 19, 26,34, 43, 45, 48 are 9mm
The 22, 23, 24, 27, 35, are .40 cal
The 20, 29, 40 are 10mm
The 21, 30, 36, 41 are .45 cal
The 37, 38, 39 are 45 GAP
The 42 is .380 cal
The 31, 32, 33 are .357 auto
Not to mention the G23 CUTAWAY, BLUE 17, BLUE 19, hut! hut! hut!
Splain this to me.
Now more on the order of release and/or development, but the first was based on Gaston Glock’s 17th patent.
Several are not imported the 25, 28, 46 etc.
A couple of times a new caliber was introduced and it came out in a 17, 19, 26 sized frame so there were sequential order. When the .40s came out the and thing but they were 17, 19, and 17L based. Then the 26 and 27 were the next US group released.
