Blast Shield
I have owned a MKii 22/45 for years, recently decided to purchase a new one, since the MKii is not threaded for a suppressor. Found they have added a "California" ( magazine) safety. Found this item when researching how to disable it. The shield is very easy to install, and now there no reason not to love the new 22/45 as much as its older brother. I would definitely recommend this item, from the time I ordered it till it arrived was a couple days, no waiting for weeks. I intend to continue purchasing from Tandemkross.

Blast Shield
Does exactly what it says...eliminates the magazine disconnect. Easy to install. Quality product. Great service.

Little Tricky but works like a champ!
Installation went MUCH easier after I realize I could keep the sear upright with an empty mag! Went to the range, no issues, worked like a charm!

Blaat Shield Disconnect
This disconnect works great with the factory trigger and firing system!!! It's easy to install if you follow the video. NOTE: IF YOU PLAN TO BUY AND INSTALL THE VOLQUARTSEN ACCURACY KIT (WHICH I HIGHLY RECOMMEND), YOU DO NOT NEED TO BUY THIS DISCONNECT. THE VOLQUARTSEN ACCURACY KIT ALREADY HAS ITS OWN DISCONNECT AS PART OF THE KIT.

Blast shield
I was slightly nervous about taking my ruger components out. This was alleviated when I watched the videos and read printed material on how to install the blast shield. The component went in fine and did exactly as advertised. I have purchased multiple TK products now and all of them have been top notch quality.

Works Great
Easy to follow video allowed me to install the magazine disconnect in about fifteen minutes. It looks and works great.

Victory Trigger
This trigger completes the Tandemizing of my Ruger Mark IV 22/45 and I couldn't be any happier. Even with my neuropothy fingers and 64 year old eyes the installation was relatively easy. I HIGHLY recommend Tandemkross.
