A Must Install
This little red piece of metal is GREAT! No more two-stepping in order to operate this pistol.

No more disconnect
Easy to install and removes that annoying magazine disconnect so hammer can be dropped when mag is removed and gun cleared.

Good to go
Part works as intended. Trigger is smoother and breaks cleaner. Firearm properly discharges without magazine. My only complaint is the installation video is outdated and does not explain how to properly disassemble the original Mark IV parts. I had to look up a separate disassembly video. The method shown in Tandemkross' video caused me to bend the original disconnect. My fault for not looking up a proper disassembly guide.

Blast Shield
Perfect replacement for the factory disconnect and spring. Does it’s intended job perfectly. Installation was a breeze and let’s be honest, the red looks awesome.

Mr.
Installation of Blast Shield was helped by good instructions from Tandemkross. Works as advertised and enjoy the Ruger Mark IV lite much more without the magazine safety.
