I finally got to shoot my RIA Tac Ultra FS HC yesterday.
I put about 200 rounds through. 100 rounds of Igman 124gr FMJ, and then about 100 of remanufactured 115gr FMJ.
The gun ran perfectly. Very accurate. Zero issues of any type. With the full length dust cover and rail and steel frame, it is nice and heavy. Barely moves when shooting it. The trigger measures 4# 12oz (5-pull average on my Wheeler digital gauge). The trigger is very nice. Short takeup. Very clean break with no creep. Nice, tactile, short reset.
I had read where mags were hard to find, but I got 4 more factory mags from Advanced Tactical, no problem. Cycled through all the mags yesterday, twice each. They all worked perfectly. And, the specs say the mags are 17 rounds, but they all held 18 and worked just fine, even for that first round coming out of the mag.
I was pretty interested in the Prodigy when it came out. But, now that I know about the Rock Island - and got one for $789 - I cannot really see any reason I would ever spend almost twice as much for the Prodigy.
I want to lighten up the trigger on this Rock, and then it will be ready to go for me to shoot it in USPSA Limited. It shoots awesome!
