You didn't specify caliber, but if you want a new production 10mm, it looks like the choices are either Nighthawk or Fusion. Based on my searches, the Fusion guns seem to have as good a reputation as Nighthawk, and are about 1/2 the cost of Nighthawk's offerings (c. $1500 vs. $3100). You can get one in kit form for well under a kilobuck.
Any input from those who own/have shot either?
Kilobuck? hahah I would guess you are an electrician. Yeah Para just makes theirs in .45. I put this purchase on the backburner for now I have an AR build that has taken precedence and I have this need for a Marlin guide gun that just won't go away. Thanks for the info guys ill check back at this thread when I am ready to make this purchase. I gotta check out those fusions.
