- Also for CE users, gave the L85A3 a functioning Grip Pod™.

Small update, adds a few new niche weapons for certain categories.

Added:
- S&W 1854 (Red dot and scoped variants)
- S&W M&W R8 (8 round revolver)
- G11 K2 (Caseless assault rifle, hyperburst only due to limitations)
- Chiappa Triple Threat (Rare triple barrel shotgun)

[Combat Extended] General Machinegun buffs.

Changed:
- KAC LAMG has reduced recoil.
- All MGs have lowered cooldown and warmup times, this change will possibly make it into CE itself.

Fixed a harmless error on startup that happened if Vanilla Expanded Framework wasn't enabled.

Added:
- A certain secret shotgun has returned from older versions of the mod, now with many more attachments.

Changed:
- Completely rebalanced the Beretta M9A3, now has a compensator instead of a suppressor and features a red dot sight and laser light. This brings it from one of the worst pistols in the mod to one of the best. Updated preview image.

- Fixed a typo in the Browning Auto-5's label. How this was unnoticed for this long is beyond me.

- (CE) Pistols with laser lights now have reduced sway to make them actually useful.
