Nice to see another Independent keeping the Browncoat tradition alive.
Small detail to point out though: You shouldn't call your Mal pistol a "Model 47a" because they are not official designations and were only used to name the two all-metal replicas made by a fellow called "Badger" on fireflyprops.net. 47 was his first version (about 16 exist) and the 47a (about 40 exist) was the second. If you refer to your copy as such, you risk spreading confusion and if you ever decide to sell it under that name you also risk getting into trouble if someone thinks they are getting something completely different.
