Just days ago I got a RIA52008 (10mm 6" 8 round PRO Match) pistol and today I shot it with 100 rounds of Underwood 155 grain JHP using factory and MecGar magazines. No any hiccups or other undesirable surprises. Each and every single round was fed, fired and ejected perfectly. I was very happy with the results. Highly recommended!
As for that Girsan, I had sold it at Gunbroker at a minor loss.
