Pros:

- nicely modeled Thompson (Or Tommy Gun, if you prefer)
- good texture with specular mapping

Cons:

- no laser sight attachment

Conclusion:

Overall a great replacement for the AK, the only thing I would recommend is adding a laser sight attachment to the model so when you have it equipped to it there isn't just a red beam of light shooting out from just underneath the barrel. 

Pros:

- nice model
- great concept

Cons:

- none

Conclusion:

It's a bit larger than Fallout canon Stimpacks, but given what you're working with out can't really help that. It would also be great if you can add a custom animation that removed the cap removal animation and went straight to injecting the Stimpack, but it's not that big of a deal. Either way, a great mod.
