Every year around SHOT these dumb Glock rumors pop up and every year they're not true.
Not anymore, really, but they probably question its sales viability in markets where it would be competing head-to-head against the identical 26.
If I'm not mistaken, the 25 and 28 were specifically targeted at the Brazilian market, which placed a .380/.38 Spl ceiling on handgun cartridges.
Some folks on Reddit came across this, G41 is a 5.3" barrel .45acp.
Since I have precisely...zero...problems carrying my G19 concealed (and can very comfortably carry my G17, G21, and G34 similarly), I have absolutely ...zero...interest in any .380 from Glock, or anyone else for that matter from a practical standpoint.
A single-stack 9mm or .45 ACP could be another matter altogether, however...
