Reviews on Grabagun for the Hudson seem pretty positive. Most other retailers are selling the pistol for $730 and higher.
Don't know if any manufacturer bought out the company and thus will stand behind the pistols if there are warranty issues.
Grab a gun has them at 799.00 now. I would have snagged 1 for 599.00 .
