Look at some of the closeups of this entry level Remington1911.
I may be wrong but the pebbly looking areas on the parts and frame might be evidence of MIM parts. On the thumb safety you can even see where a burr was ground off (the straight scratches) but other sections of the safety look they were 'cast'. I'd think the rough sandy look to the metal's surface would be from the finish if there wasn't this evidence of machining too.
The frame itself looks pebbly, too. If given the chance I'd prefer a forged slide and frame. But how can you even tell on some guns with a lot of machining to smooth them out and a thick duracoat what have you hiding the evidence? Is my parkerized Springfield MIM framed? Dunno. I kinda doubt the Colt is, but I don't know for sure.
The pistol is priced at entry-level... uh... levels, and you gotta expect a good bit of cheaper to manufacture Metal Injection Molding components and less finish work to the surfaces.
