My tax refund is soon to come back so of course I have my next gun all picked out. It is a RIA 9mm style 1911. Only problem is the only way to get that gun is with a TCM barrel. I do not want the extra barrel, I know nothing about TCM and I don.t want to pay the extra it costs. Midway USA where I get most of my ammo does not have any TCM ammo. I can get it from some places so my question is is the extra barrel worth the cost. Has anyone shot much of this stuff.
