In regards to the trials Glocks... the 19X is the gun without the safety. I doubt Glock will publicly do any of their pistols with an external safety.

Whenever Glock publicly releases the 47... you’ll have pretty close to the full size of the trials gun; again, without the safety. Unsure if they will be marked DHS, but from what has been said... they will put them out once CBP finishes the move from H&Ks.
