looks like it was re-engineered to be straight blowback (NO locking system), like a glock 25 (17 sized in 380).
Locked breech with a 380 requires a very light (LCP / glock 42) slide.
different front sight likely due to no tilting barrel or different recoil energy / barrel exit time of the .380.
Blowbacks always seem to kick more than youd expect for such weak calibers. (my cz83 feels like it kicks the same or more than a p365 despite the 83 being heavier and a less energetic round)
Its not just Mexico, a good deal of Latin America restricts military or max out legal caliber at .380
Its hard to get .380 pistols imported here (point test, pocket pistol rounds are disfavored)... the Glock 25 fails the point test in /380, ALL Glock 42s are usa made. While this thing would still likely pass due to its weight, i doubt we'd ever see it (more expensive ammo, likely kicks the same, same capacity, not legal in uspsa)
(meanwhile in Canada, before the latest schenanigans, .380 is the MINIMUM cf pistol caliber)
