The 9mm compact Glock 19 and .40 S&W compact Glock 23 will both be offered with the Rough Textured Frame (RTF2). This frame does not replace the standard Glock frame, better known as the 3rd Gen Frame, on the G19 and G23, but will be available as an option.
From the press release:
The G19 and G23 are two of the most popular GLOCK models. The G19 9×19 compact is widely used all over the world. In addition, the G23 in .40 caliber is quite popular with both law enforcement and private individuals as a back up or concealed carry firearm. Adding the RTF2 finish to these compact models increases the options for law abiding
individuals and organizations. Along with the new RTF2 finish, each of these GLOCK pistols have the same time tested “Safe Action” system, durable exterior finish, cold hammer forged barrel, durability, reliability, and light weight that GLOCK is famous for.
