The New MCK Trigger Guard Comes in three different models. The MCKTG1 for the MCK Glock, the MCKTG2 for the MCKGEN2 Glock, and the MCKTGU for all other MCK models such as Sig Sauer, Springfield, Smith &Wesson, etc. This now allows the trigger to be physically covered while transporting your MCK.
* Please see compatibility chart
* TGU Slides on to the side Rail. It does not clip like the other 2 models
