Rackman, as you created this thread and asked for opinions, comments, etc. on US vs German Sigs, which you received from many long term CGN members.
Why do you argue, ignore and dispute a number of very similar comments on this question/issue from members on here that have a lot of knowledge on this topic?
Besides, you even mention above "I mean, I'm no expert, I don't have formal training in firearm design or manufacturing". So perhaps you should listen a bit to those that do! He**, you even dipute and ignore a former Sig executive's (Mr. Green)comments on the very issue your asked input on!!!
I see you purchased a US made Sig 1911, which is a very nice pistol, in fact I think it is one of the better 1911 clones out there.
Your question does not even apply to that pistol, as it was never made in Germany!
So, enjoy your new Sig and be done with it.
I own 8 pistols, two German made Sigs and four German made H&Ks, an early 80's Colt CGNM 1911 and an Isreal made DE (just for fun).
As I mentioned in my earlier post in this thread, I had a chance to purchase two new fully German made/assembled 2XX Sigs for the same price as the US made counterparts.
Knowing that the German guns main parts (frame, slide and barrel) are matched at the start of production and then handfitted by skilled gunsmiths, using all 'in house' made parts, it was an easy decision to purchase these guns instead of a US gun.
HK still manufacturer all of their gun parts in house, all of theit guns, apart from the HK45, which is only assembled in the US using German made parts, are all fully German made.
A HK representative I met recently, joked to me that they are very, very reluctant to trust the US to produce their guns after seeing what happened to Sigs quality!!!
This is not "hearsay", I met the German HK military arms rep. on a flight home and we chatted for about an hour about HK guns when he made the above statement.
Ever thought why even Glock still make all of their guns in Austria and have not opened a plant in the US?
From my working experience (QA Auditor) with the US manufacturing industry, if they can find an easier, cheaper way to make a part, using a material that will just meet specification, they will! And we all know they struggle with QA on a fairly regular basis.
Again, just enjoy your Sig 1911.
