Generally agree.
- R301, I wouldn't touch the damage, I'd tweak the handling characteristics.
- I think the P2020's an easy buff target.
- I think the Hemlock isn't that great, but would be if other weapons were toned down like you advise.
Regarding the Prowler, for me, I'd rather it started in full-auto mode and that the select-fire hopup added the burst mode, perhaps tweaked to have less recoil than it currently does now (to make the 'upgrade' worthwhile). Picking up the gun on the off-chance you find the alternate fire hop-up is just too risky compared to the alternatives, most times.
