I own 2 Rossi Rifles the M92 in 45 Colt and Rio Grande in 45-70. Had a minor problem with the M92 called Rossi, got a return label on the same day and had the gun back repaired in 5 business days working perfectly. Rio Grande is the best fit and finish gun I've ever owned and I own a lot of guns in 47 years owning guns.
Now as for their auto pistols (never owned one of their revolvers) I have a PT92, PT911, and a PT 111 Pro. All three have been shot a lot well over 1000 rounds at least. Never had a problem with any of them.
I've also owned Colts, S&W, Ruger, Armscor, Remington, CZ, Sigs and others some had problems with mixed results on repairs. Rossi/Taurus over the last year seems to have better QC and service faster if needed. The single best CS I found with all of them is Armscor bar none but Rossi/Taurus and Ruger are also high on my list.
