The item works as described and installation is easy. Really like this item.

Mag disconnect
Does what it is supposed to do and deletes the stupid mag disconnect. Straightforward install, video was pretty decent to guide you through. I also removed the right side of the safety during the install.

Mag Disconnect Replacement
This product works as advertised and was easy to install. It is easy to flip up so you can clean the sear. Did not noticeably affect trigger pull weight on my pistol.

Mk IV - 22/45 Blast Shield
Great upgrade for my MK IV. I wished my MK IV would functioned like my 5 1/4" heavy tapered MK II 22/45 and now it does. IMO your products offer function and reliability improvements to my firearm (s). Thank you.

Blast shield
The mkIV as good as it is has some hiccups, however this greatly remedies those issues. Magazines seat so much better. Great construction and Tandemkross has videos of installing it,so if anyone has hesitations the video helps out alot

Was fairly easy to install using the video, eliminated the magazine safety perfectly! Would buy it again.

Nice product!
This thing is a bit of a pain in the ass to install. The Tandemkross video needs to be more clear that you don't reuse the spring. I like not having to have a mag in my gun to fire it. Not even for actual use but some times you just want to work the action without having to grab a mag, or even empty out a mag. This does the job and is pretty cheap.
