Thanks shooter.
It looks as though it doesn't haven't a feed ramp (desc you gave is exactly what is there, smooth except for the rivet on the left side).
I checked out those sites, looks like they're gettin' a pretty good chunk of change for the conversions. For now, I think I'll just buy a 10rd mag, make sure it does work, then buy a few more and leave the gun alone until I'm ready to upgrade.
I knew I'd get an answer quick, thanks! Now I gotta find some 10rd mags. Any ideas for some cheap mags? Cheapest I've seen on the web has been $19.99 for the 10rd.
