Recently purchased a LNIB Rohrbaugh R9 from Gunbroker and was able to take it to the range yesterday. I was very impressed with the little R9 on the range, it ran flawlessly and was very accurate for such a small pistol.
I ran several different brands and grain weights through the R9 and they all ran without a hitch. I used Gold Dot 124gr, HST 147gr, V-Crown 124gr and Black Label Ammo Inc 115gr. I ran a about a magazine of each, accept for the Gold Dots, which I ran two magazines. I intend to carry the Gold Dots, since they are recommended and seemed to have the least amount of recoil accept for the Black Label.
I was a little concerned that I may have malfunctions with the R9, being a used firearm that I was buying from an online dealer. I just recently purchased a used Bond Arms Bullpup, but had to send it back to Bond Arms due to multiple feed issues.
Very happy with the R9 and intend to carry it as my off duty firearm. It's a shame that they are not still manufactured. I'm also a huge Seecamp fan, I've carried a Seecamp 32 and 380 daily for approximately 15 years. It would be awesome to see Seecamp start producing the R9.
