I have a Shadow Systems MR920 Combat frame that is complete with all internal parts and the factory magwell (not included on the less expensive Foundation series). This is the same size as the Glock 19 G19 and is equivalent to the Gen4 series.
This will accept all Glock 19 slides from Gen2 to Gen5.
I will meet in person in front of the Mesquite police department at 777 North Galloway Ave. Valid TX LTC gets $10 off. Valid TX ID is required.
