The Redline designation pairs here with an aftermarket American-flag slide finish featuring a gray/black pattern and a bold red stripe. The result is a distinctive look while retaining the proven P365 micro-compact form factor.
The pistol is striker-fired with a 3.1" barrel and a stainless steel receiver housed in a black polymer grip module. Front and rear slide serrations aid manipulation, and a proprietary accessory rail is molded into the frame.
Sights are fixed iron: a front post with a green dot marked TG-H3 and a rear square-notch marked 628. The setup is straightforward and durable for everyday carry or range use.
It ships with one 15-round steel magazine featuring witness holes labeled 5/10/15 and an extended baseplate, giving the pistol a 15+1 capacity. A Hogue rubber grip sleeve is installed for added purchase, and a spare SIG P365 grip module—also sleeved—is included.
Additional details include U.S. manufacture with the frame marked "NEWINGTON, NH USA." The factory case label is dated 19-AUG-2019, and the FCU serial number matches the case label.
