-1,
Maybe I made a mistake of referencing DPS on your post Bane, but it truly isn't your standard DPS most think about when playing other shooters.
When balancing weapons in GMOD, DPS isn't always the best metric. Other variables such as tick rate, RPM, lag, hit boxes, recoil, spread etc.; all have a large effect on the viability of a weapon. Therefore, the balancing of these weapons gets harder and harder to satisfy as the comparisons between themselves are brought up.
I don't see the utility of making only a single change in this case. I'd rather someone lobby for a re-look at base loadout stats in general, and take it from there.
If you feel as though its impacting your game play this much anyways, I'd speak to GM's about lowering the health of their NPCs.
TL;DR -
Seems like you misunderstand the weight of DPS in weapon balancing. Without any clear balancing issues currently, I see no need to tamper with your weapons stats. If that is something to be done, I'd rather it done while looking at ALL base loadout weapons.
