I made a project out of a couple of these. I even changed the barrel in two. One was a drop in, the other required a lot of hand fitting.
I dabbled with cast bullets, but never really found a combo that worked.
Handloading is pretty straight forward, LEE dies for the 38 Long/Short Colt work, as do some other combos of 9mm Luger and 38 Special.
Beware: if you handload, PRVI brass is thinner and lighter than some other stuff, like shortened 38 Super, back off on the powder. PRVI ammo and brass are OK, I was not able to reach factory velocities, close but I'd back down when the cases would show the Glock bulge.
Perhaps a good time to sell mine, and the several hundred rounds of 1F Norma brass. I jumped up 8 years and shoot a 1911 now.
