I posted more details of my experience on the 1911 forum site, but my experience has been anything but satisfactory.
Bought the generic RIA 1911, took it to the indoor range, withi I believe 5 different brands of ammo. Magtech, WWB, Fiocchi, American Eagle, and CCI Blazer.
A constant stream of FTRTB's, with the slide about 1/4" from returning to where it should. Interestingly enough, the CCI Blazer aluminum stuff worked fine for 2 full magazines.
Most FTRTB's were when transitioning from the 6th to the 7th cartridge in the mag. I didn't whack the slide hard to get it to close, just pulled it back a bit, and let the spring push it home, and that seemed to work.
No FTE's, in fact, one of the brass flew about 12 feet into the air and broke out the flourescent light overhead. Brass was strewn in a huge circle 12-15 feet left and 3-4 feet behind me.
After the first 200 rounds, I went home ticked, posted on the 1911 forums, and was advised by the factory guy that I needed to worry abotu it when I had 500 rounds through it. Like somehow that money for the first 500 rounds is apparently just grown on trees.
Anyway, another 150 rounds later after polishing off almost all the ammo I own, I'm down to 1 FTRTB every couple of mags (only have the 1), and the onlyo thing working perfectly is CCI Blazer.
I did not try any high-end ammo, as I fail to see why I should throw good money after bad.
So in upshot, by the time I get my 500 rounds in, plus the cost of the pistol, I could've bought a better quality pistol out of the trenches and saved myself much aggravation.
And of course, it's still not working perfectly yet, so the jury is still out on whether it hits the for-sale section here pretty soon... Darn POS.
Ask me again in another couple boxes, I'm counting down to 500, and if it ain't working pretty darn good at 501, I'm gonna raise some cain at RIA, and see if that factory support is as good as I hear.
Would I do it again? No. I should've just bought the PT1911, it was sitting there, right next to it, or the used DW they had... Oh well, live, and learn what to avoid.
