RE: After market gunsmithing
I'd suggest polling friends who are shooting NUTS...like gun club members...and find out a reputable smith that they use.
I'm from Michigan so have no advice for you re: smiths in Texas....but I've learned over the years that the biggest and the smallest outfits are usually not you best bets...
I have been lucky enough to find a smith in mid Michigan that does good work at a reasonable price in a timely manner ...and he stands completely behind everything he touches. A rare find these days.
