SAM or Norkie. Boils down to your preference between the precision CNC machined cast 4140 steel SAM or conventional machined forged high tensile strength steel Norkie. Really, what's a few ten thousandths of an inch give or take between SAM and a Norkie? After all the original 1911s were probably built on leather belt driven lathes and milling machines and Sgt York shot 7 for 7 for a perfect score and won a Congressional Medal of Honor with the help of his 1911. I went with and will always go with the better steel. Norkies in my safe 4...SAM zero. That's a personal preference only. If the price difference does't bother you (really 150 bucks is not much ammo anyway) and you like the smoother finish of the SAM, go for it. You'll be happy with it for sure. SAM is a very experienced firearms manufacturer in the Phililppines so again no real debate here....SAM and Norkie are both good manufacturers.
Pretty decent overview.
I prefer the stainless, so that pushes me towards the SAM. Yes, the Norcs are built by hand, and normally that shouldn't be an issue AT ALL, after all, most firearms and most 1911's were built on manual machines. But, I've heard it said that to get the highest levels of reliability out of 1911's, either requires a really good smith to slick up the action, look for imperfections, OR you can pick a CNC'ed unit and just do your own polishing of surfaces. Personally, I think by the time you factor in a smith's time, the cost difference would be a wash really. I'd bet both the SAM and Norc are similarly accurate, and could be tuned for even tighter accuracy if needed.
The forging vs casting issue might be an issue if I were building a competition IPSC racegun to pound out 100,000 rounds...I might go with the Norc frame. But although I plan to shoot a lot through a SAM, it'll be NOTHING like those numbers, and I suspect SAM knows how to make good castings, probably done so for a very long time now.
I think some Norc 1911's look better than others...those two tone .45's (sport model??) look MUCH nicer than the bog standard NP-29 9mm, which after handling one left me wondering if I really wanted such a homely looking handgun, when the visually nice SAM's were just a bit more money. And I think the Norc blued A1's also look quite decent too. But, I'm looking for stainless and 9mm, and since 9mm has less recoil impulse, I'm even less concerned about the frame being cast than forged! But if I were looking to buy a .45 for high mileage, I'd take serious consideration of the two tone Norc Sport models, or the blued A1 and put some nice grips on them, slick them up myself.
What I didn't care for on the NP-29 included: mag release is WAY oversize and looks like it would be easily bumped at inopportune time, the slide release seemed overly large and unessisary, the finish was...well not as nice in person as I thought it'd be, didn't care for the slide serations, safety overly large, rear iron sight looks awkward and sharp. But really that's all kinda nitpicking for a reliable handgun for such low price...I just was much more impressed with the SAM is all. And i know that other Norc 1911's are nicer than the NP-29. Now...if Norinco were to make stainless 1911's...but maybe that's unrealistic at those prices.
One downside to the Norinco steel: apparently it's so hard that SOME smiths aren't interested in milling the slide for a different rear sight. But there's others who can and will do a good job, so again, a downside, but a very minor one requiring maybe a few more phone calls!
