I'm sure a few people probably have tried a TRX3.3 in their MT2...
However for the price you pay for a TRX3.3, you are much better off getting either an .18 OS CV-R or .18 TZ...either will work out cheaper...performance of the CV-R I would estimate to be approx equivalent to the TRX (maybe the CV-R has a little more???) and the TZ will totally blow the TRX3.3 out of the water!
