saiga tbone

I have two Saiga's that I really like. A 762 and the 223. I'm an amateur at best, but I've put the Tapco stocks and pistol grips on both as well as a new fore arm on the 762 and modified the one on the 223 myself, just for kicks. I've read everything I could find on the trigger conversions and don't think I could do it myself. My question is, why or why not do the trigger. What are the pros and cons. Thanks in advance for any advice.

Recently purchased the x39. Replaced all of the furniture with Tapco products. Didn't touch the trigger or anything else. I only changed out the stock, with the Tapco extender and the fore arm. Using the mags for the Saiga from Arms of America. Am I compliant. Somewhat confused on these compliance issues. Thanks for the help.
