For Glock 21 BBL THD BLK NIT 45 ACP
Hi Bryan, this will fit the Gen 5, but model 078000552 is for the non-threaded barrel. The threaded barrel is 078000553, but they both have the same UPC 050806113145.
I would contact Bud's to confirm whether or not this has a threaded barrel. 1-859-368-0371 9am-9pm EST Mon-Fri. or use the Blue Chat now button at the bottom right corner 9am to 8pm Mon - Fri
Stay safe & have a great day!
