Opposing Force v_desert_eagle?

may one of you be able to convert the deagle from opposing force into the source engine? i was planning on making a swep for it i already have the textures for it but i don’t know how to convert the model to the source engine.

Silverlan already made a swep out of it.

i know that, and its going to be awhile before he releases that new resistance pack, i was just wondering if i could have it compiled before hand
