Rost Martin RM1CX Tactical

The Rost Martin RM1CX Tactical is the threaded-barrel model in the RM1X series. It keeps the line's shared architecture, a compact slide over the full-size RM1F grip at 5.1 inches tall and 1.2 inches wide, and adds the two things a suppressor host needs: a 1/2x28-threaded hammer-forged barrel and sights tall enough to be seen over a can or an optic.

That combination is the reason the Tactical is the interesting model of the three for anyone already running a 9mm suppressor. A threaded barrel from the factory removes the usual aftermarket step on a budget pistol, where a replacement threaded barrel often costs a meaningful fraction of the gun. The taller sights matter just as much and are more often forgotten: standard-height irons disappear behind a suppressor, so a factory pistol that ships with suppressor-height sights saves a second purchase.

The magazine pairing is the one place the Tactical departs from the base gun. Rost Martin lists it with two 10-round or two 24-round magazines rather than the 17 and 19 that come with the standard RM1CX, so the pair a buyer receives depends on which configuration they order.
