Big Rock Sports (BRS) has a compact semi-automatic pistol named the Remington RM380 listed in their database (see above). All we know about this gun is that it is chambered in .380 ACP, takes 6-round magazines and has a MSRP of $410 (UPC 885293964549)
The MSRP suggests this may be a .380 ACP version of the 9mm Remington R51. On the other hand, Remington may be introducing a polymer sub-compact to complete with the Ruger LCP, Kel-Tec P-3AT and Glock 42. Time will tell.
Note: this has not been independently confirmed by a second source.
Thanks to Chase for the tip.
