Congrats on your new find. The Night Guard series is one of my favorite.
All the NG's are relatively rare as they were only made for a few years & in limited quantities. Pricing is commonly suggested as the reason for their short production run. (See MSRP below.)
The 325NG was one of the original six introduced in 2008 & it's my belief it's likely the most common of the NGs made.
I replaced the (dead) front night sight with a red ramp & swapped out the C&S fixed rear for an adjustable on my 325NG (which I've also done to my 357NG now).
My 325NG shoots 45ACP rounds reliably individually loaded (though I would not suggest doing so for SD use) as well as with metal or polyster moon clips. I mainly shoot handloaded 45 AR (Auto Rims) in my 45ACP revolvers though.
Some have benefitted from an extra length firing pin (C&S or Apex), as mine did.
I also shoot 45 Super power handloads in it either using Starline 45 Super brass or Starline 45 AR, both of equal strenght.
Hope you enjoy your's.
