Ihue, I don't think I have ever wanted to fire 80 rounds from the Rohrbaugh in one session. When I was breaking mine in, I would shoot about 30 rounds or so, at the beginning of the shooting session, and then gratefully go on to other heavier pistols, either 9mms or .45s for the rest of the session. Even so, thirty rounds with the R9s makes my trigger finger sore, not from squeezing the trigger, but from having the pistol raise "briskly" and hit that finger on the bottom side of the finger, even with a very firm two-handed grip.
Now that it's broken in, I don't fire it all that much, just a magazine or two every now and again, to stay familiar with it. Honestly, it's not a pistol I usually look forward to firing, unlike larger guns. But I do like the Rohrbaugh a lot, and appreciate how beautifully it is made and how easily it will completely disappear into a pocket with a pocket holster.
Unlike some others here, I almost always use the Rohrbaugh as a back-up, not a primary. I personally like 9mms a lot for their easy recoil and fast follow-ups, but recoil from a Rohrbaugh is not something I'd classify as "easy" by any means, it sure lets you know it's been fired! And I feel I shoot heavier pistols with longer barrels and sighting planes better than my "little beast." Still, I'm glad I have it, because as far as I'm concerned it fulfills the role of an accurate, small light pocket pistol better than any other.
