I had a serious problem with one of my 3 R9s which was promptly corrected at the factory to my great satisfaction. Kudos and all credit to the Rohrbaughs.
The R9 is still my EDC. I have a Boberg XR9 and XR9L and they are both quality weapons and fun to shoot. I cannot imagine why someone would not like one, but each to his own. The shorty carries very well in a DeSantis Superfly front pocket holster, but is larger than the R9, and a little less suited to my clothing in Florida. My recommendation is to follow my lead and own and carry a Seecamp, an R9, and an XR9 variably depending on season, clothing and expectations. Keep the contact .45 for when you are feeling fey....just gotta practice with each to be sure the various techniques are grooved before you switch from one to another. Keep the big guns around for range fun and home protection. Simple, huh?
