I have my stamp in for an AAC Ti-Rant 9. Primary use will be on my SIG MPX Gen 2 9mm SBR. However, I am also considering a dedicated pistol for a host for the AAC Ti-Rant 9. I do not plan on "carrying" the pistol and suppressor combo - this will be a range toy only.
Option 1: take one of my 9mm M&Ps, etc. and buy threaded barrel and suppressor sights. Cheaper but barrel plus sights is still pricey.
Option 2: buy a "suppressor host" factory 9mm pistol - SIG 320, CZ P07, CZ P09, M&P. Example, seen used CZ P09 "suppressor ready" for $500 in Atlanta area.
Option 3: buy a factory 9mm pistol with red dot cut, install a red dot, buy a threaded barrel. Excuse to get into a pistol with red dot. SIG RX series or Glock MOS?
Feedback? Again, range toy.
