I bought from bear13 earlier this summer and thought he was GTG, so I bought a used trigger from him in August. It arrived on 8/25 but arrived without any pins (trigger or hammer).

I PMed him a couple of times before he responded. On 8/29 he promised to send them out "tomorrow."

I messaged him a few more times since pins never came but he hasn't replied. Not a huge loss, but I would steer clear of future deals with bear13.
