Thanks for the tips - I've been using a similar strategy and monitoring all of the servers' GTNs, but haven't been able to find these pistols yet. I do have enough credits to make a reasonable offer and am willing to transfer servers as needed to make a purchase.

I've been having trouble rounding out my collection of the BoE versions of the Esstran weapons, particularly in trying to find copies of Fortitude or Grit. Hoping that the forums can help - please PM me if you have one of these pistols to sell so that we can talk prices and arrange a time. Thanks in advance!

Just found this on the market, and I think it deserves a mention: S-311 Fusion Saboteur It's BoE, so I'd guess that it's a random world drop - probably from the Belsavis Heroic Daily areas. Especially cool in that it looks almost exactly like the rifles that a lot of the Republic forces use.
