Hey yall! I'm new to the board and new to the world of Class III and SMG/SBR's. I have been doing some reading and looking around. For my first purchase I'm looking at a Mac or some sort. However, as many of you know, there are a number of choices when it comes to these. I found a Texas Mac for sale, its a 10A1. I think its semi though. Can anyone tell me how to find out if this is one of the early Texas Mac that was tack welded or if this is one of the later made texas macs from the buyout that is TIG welded? I would prefer a .45 or 9mm over the .380 Any recommendations from owners to a specific manufacturer? RPB? SWD? etc... Is there any other good site to try and find out more info on these and which model, production years are the more desireable ones? Thanks in advance guys!
