We give you, the Rattail One-Nine
Serious former operator turned performance shooter Kyle Defoor once cut down the frame of a full-size Glock 17 to accommodate the shorter 15 round G19 mags. This essentially gave him a G19 with a longer barrel and sight radius.
Now he did the same thing with a G19– chopping the frame down to accept the 10-shot squat G26 mag. He dubs the custom Glock 1926 hybrid the “rattail one nine”
If you remember your Glocks, the 26 “Baby Glock” subcompact does not have a rail, has a 3.42-inch barrel and a 5.39-inch sight radius, whereas the G19 does have a rail and adds a bit more than a half-inch to both the barrel and SR.
Kind of interesting, especially with the hi-profile night sights, KKM barrel and Surefire XC1 LED attached. In short (see what I did there), you have a G26 that accommodates.
