I've not dealt with RIA's customer service... but I haven't had to. I've had two GI models. One from around 15 years ago and one I purchased recently (I honestly didn't like the tactical other than the sights... plus getting a 1911 for a little under $400.00 is a big benefit).
My old one was flawless for I don't know how many rounds... at least 2k or 3k. I didn't want to sell it but I did because of hard times and I needed to keep my carry gun (which I actually liked less, but I would carry it). The trigger was amazing in it. The only thing that was off (looking back) is that the finish was a little crude on it. My new one? The finish looks much better on it, but I don't think the trigger is as nice. Not bad, but not as nice as the trigger in my old one. I only have a few hundred rounds through it, but it has been functionally flawless. Many 1911's start to have issues with HP ammo... neither of my RIA's have had any issues with any ammo including Winchester Ranger HP ammo.
So... in summary you should get one but not from Cabela's. There are better prices.
