Yeah, I am considering sending it back to Rohrbaugh; that is one of the options.
So far, I did shoot two mags of ammo before the jamming. As of now, even with a clean gun, plenty of lube, carefylly loaded mag, I cannot get the first rnd to reliably strip off.
I did find that if I place one (1) rnd in the mag, the feeding goes 'OK', but with three, four, or six, in the mags... JAM!
I do suspect either the follower or that ramp angle.
