Bored on break, started googling .460 Rowland (mostly because I thought how fun would it be to have a .460 Rowland Roland Special) and saw on their website they have .960 Rowland conversions for glock 19s.
Shoots the .960 Rowland using standard magazines and everything. Just new barrel, but can also shoot standard 9mm
From their website...
"deliver a 115gr bullet downrange at 1600 ft/sec, and a 147gr bullet at over 1400 ft/second"
Oh and a 15 round glock 19 mag holds 15 rounds of 960 Rowland
