im confused about a trigger frame?

[mini_marc_mag]

i just saw a guy that had a really sweet mini, so I started talking with him and I realised that he had and e-frame but not any frame it did'nt have any shooting modes on it , only game timer and crap like that but the trigger pull on it was so close that i could'nt see the space between the trigger and the frame so i ask him where he got it and he bout it from a friend ,so im wondering if anyone know what trigger frame that was!!

it was probably a grip it self with the timer, and the gun wasn't gassed up so it made it look like it had a short trigger pull.
