A friend is Installing the Trijicon RMR, adjustable model, on Glock 19 MOS. Am able to get the proper screws to mount the RMR at the hardware store. Any opinions on the hardware store v. the installation kit? Is the shim necessary? Also, wondering if anyone had any opinions on the Caliber Dynamics Tomahawk flat trigger? The ability to adjust pre and over travel seems very appealing.
Thanks in Advance
