I have toyed with the idea of fitting a round butt grip frame to a 4 5/8" Ruger single-ten—the one that comes with the big fiber optic sights all around, and socking it away against future decades.
Fat sights for old guy eyes, check.
Zero recoil, check.
A trigger that anyone who can still move their fingers can use, check.
Cheap ammo for fixed-income practice, check.
Future-proof legislation-resistant optics (as much as anything can be future-proof, in terms of politics), check.
Sure, it’s only 10 rounds of weenie CCI stinger, and then done, but it beats nothing by a long shot.
JMO.
