I've always preferred the low definition models for the gold source Half-Life games compared to the HD/SD/UD ones. But even then some of the models from the first game are a little too LD for me, with the Gearbox ones being higher quality. So I've started working on some of that.
This is a minor adjustment to the Valve's retail Barney model, replacing his lower-definition glock model with the better low-def model made by Gearbox and used by the Hgrunt medics in Half-Life: Opposing Force.
Includes versions for Half-Life, Opposing Force, and Blue Shift.
Its good but looks crooked. I would suggest modifying the hand mesh on the "weapon in hand" bodygroup and extending/stretching the "fingers" to wrap the grip more properly. A very simple edit that can bring this up considerably.
