The checkered front strap on my TB is almost uncomfortable it's cut so sharp, the gun itself would only take ACT mags...frame was too long in the front for Mecgar/metalform to seat, and the magwell kept Elander mags from fitting as well. The front sight white plastic insert is pretty useless too and dull compared to the painted back dots....but why 3 dots on target sights anyway? Should be black all around, or black rear/fo front. The ambi safety is too thick on the right hand side that no other grips would fit without modding. Anyway at $520 sale price, I didn't mind fixing up a few "issues". At $900 it would have been sent back.....and I would have gone the Spartan route.
Everything else is tight and it shoots well, but it's no tighter or better trigger then my Omega or Commander, so I doubt there is any extra work done on these. I'd actually say my commander has been the closest to being perfect out of the box, and it was the cheapest of the 3 SAMS I own lol
