Finally did it, bought a Rock Island 1911 2 tone (the dark slide). Before you start trashing my purchase, it was a good price for an unfired pistol and the machining and fit is well above what I expected for the price and country of manufacture.

Just one problem, the chamber needs to be throated. Round nose ball ammo feeds well, but the LTC bullets I load hang up and result in a failure to return to battery unless they are seated rather deep. I could return the pistol for warranty (weeks or more) or buy an aftermarket barrel but I'd rather have someone that knows what they're doing ream the chamber.

So, my question: anyone recommend a good smith in the Stroudsburg or Trexlertown area (or in between) that can take care of this without bending me over the work bench or taking weeks to do it?

I got to admit, I do like the gun.

I'd say get the feed ramp polished, or do it yourself with a dremel. Then a heavier recoil spring if you're still having problems. Should feed just about anything. If all else fails though it's usually the magazines. Buy some wilson combats or something and be done with it.

My RIA seems to feed Hornady TAP FPD hollow points with no problems.
I haven't tried anything else besides FMJ.

RIA makes really nice guns for the money. I would not hesitate to buy another.

Boy, tough crowd!

Here's Rocky:

   

   
Lead Truncated Cone ... In spec and works well in my LLama Onmi.

   
You can see the line where the lead stops in the chamber. If I seat the bullet so the shoulder is at or below the case mouth, the round allows the slide to go to battery. Round nose and Silvertip HP's run fine.

   
Machine work on the lower.

   
Machine work on the slide. Some of the best I've seen on a 'bargain' gun.

Yea, the grips gotta go, thinking checkered rosewood, and night sights.

What's the OAL of the LTC round versus a FMJ or the Silvertips? If you're talking about having the chamber reamed to fit the TLC's then the FMJ's or Silvertips might go too deep before they headspace and the firing pin may not make good contact. Remember that the case headspaces on the mouth of the case and if the LTC OAL is longer then it is contacting the barrel lands before the case mouth meets the end of the chamber. Or it could just be the shape of the LTC's is causing the problem with this particular .45.

The Silvertips and ball rounds both measure at 1.260 +/-.

The OAL of the LTC rounds were done at 1.225 +/- .004. I reseated a few to 1.208 +/- and they chambered well. I loaded up a few tonight at 1.200 +/- OAL so they should chamber ok. Just hope they're not so short they have feed problems.

If you google "RIA 1911 chambering problem" you get a lot of returns. The most helpful answer I found was on The High Road.org. The reply was: "You need to make a dummy round at 1.250" OAL and drop it into the chamber. This will tell you if you have a throat diameter big enough to accept that bullet. You may have a .452" throat and a .452" bullet won't chamber. You can't force a .452" bullet through a .452" hole easily." and "What *** said. In fact some throats/leades are .451" There is no way a .452" bullet will chamber correctly."

I looked inside the chamber and there is no throat, the rifling starts at full depth at the end of the chamber, no lead in. This is why I asked if anyone knew of a good smith that could throat the chamber. If the chamber was short, nothing would sit flush in the barrel ... hard ball, Silvertip or empty case.
