-Fixed the fire rate issue! I had it set to 0.857 instead of 0.0857. Special thanks to godzilla995 for pointing this error out.

BIG UPDATE
-Reduced damage to 40 from 50, reduced PenetrationPower to 67 from 70.
-Increased fire rate to the real-world accurate 0.857 (700RPM) from 0.1.
-Increased capacity to 50 from 35.
-Rebalanced SpreadPerShot, MaxSpread, and SpreadDecay to be closer to vanilla.
-Removed reload speed edit due to occasional visual glitches when reloading.
-Fixed a few errors in the stats.

I really left this weapon in a strange state, but this should be more acceptable. Will likely tweak further.

Quick update: Mag size reduced back to 35.

UPDATE:
Reduced damage from 55 to 50
Increased mag size from 35 to 40. It really was too small.
Reduced penetration layers from 3 Commons to 2.
Increased vertical recoil from 1.0 to 1.1 (vanilla = 1.2)
Increased deploy delay (time after switching to weapon before you can shoot) from 0.35 seconds to 0.48.

Tweaks to firing spread and spread recovery.

Decreased spread per shot ever so slightly.

Fixed a simple issue that was causing invisible hands on L4D1 Survivors.
