George, no, haven't bought more mags and may not. The two original mags have been working great, no problems at all, but I don't carry a spare mag for the Rohrbaugh. If Rohrbaugh ever offerers a 10 shot spare mag with a pinky finger extension, I'd buy it in a flash and use it for the second mag, but right now the Rohrbaugh is usually strictly a BUG for me, in my opinion, the world's BEST backup.
Love the gun, it's superb, but personally, I still shoot larger pistols, like compacts, better, and can reload them much faster. I've been interested in the discussion here not too long ago, about fast mag changes for the Rohrbaugh. I've tried this but am still way slower than I like.
It's not the butt latch that slows me down, I actually like that and am used to it on some other pistols. I understand why it's there on the Rohrbaugh. It's having to grasp the mag, move the latch, pull the mag out, get the new mag, then having to move the butt latch backwards again with the new mag to insert it, then rack the slide. Of course, a tactical reload would make the process faster by not having to rack the slide. Still, it's way slower than I like for me.
And hah, who says we don't have full discussions of both the good and bad about this great little piece.
