Sure! I had planned on completely redoing the models, as I'm doing with pretty much everything else. I've already got both of the weapons "voxelized" so once they are done, I'll send out the update!
Thanks for the report! Going to do some work on the game today, fix some bugs and hopefully release the update with the new models. We also have a trello page, in where you can post suggestions and bugs there as well! https://trello.com/b/KVxTiACn/voxelstein-ue
