Currently trusight is relatively niche in use, besides the price it's due to the fact that you need to aim it first at someone before entering combat for the effect to kick in. This means in a lot of combat situations you just flat out won't be able to use it, and it really feels like it was designed for sniper use more than anything.
But as now melee weapons can get pretty substantial buffs, TruSight is the closest equivalent for guns for that, and yet it remains expensive (besides mod and it's installation, you also need goggles/chrome) and extremely situational tool and I think it could use some love for that reason.
My proposal is simple, while it will lock on still with aim just fine, also give it a "lock" verb to set it onto a specific target during combat, and change it freely as combat goes. This way it will see more use, and just like melee weapons, gun users got that premium-spend option for a bit of a buff.
