It is a fine article expressing one man's opinion. Yes, Mr. Yam knows his pistols, and 1911's in particular, but it is still his opinion. My opinion is somewhat different.
I have carried, competed and smithed 1911's for many years, and like many of us in the "older" crowd, I was a revolver shooter both as a daily carry gun and in competition. I have carried, competed and shot a number of polymer pistols, including an XDs, an XDm 3.8 & 5,25 in 9mm, both of which have been extensive modified for use in competition, Glock 19, H & K's, etc. That being said, I have never seen a type of firearm that did not eventually fail. Training with the Illinois State Police, several of their Glock 22's were out for the count after crawling around in mud and sand for 1/2 a day. I have seen Glock 19's lock up at the range. XDm's, even with PRP striker retainer pins, fail catastrophically when that pin breaks or becomes damaged, and the list goes on. I have had 2 Kimbers, neither was 100% with JHP's. That is why we train for malfunctions. And yes, revolvers fail as well. Just ask someone who has carried a duty S & W what happens when the ejector rod backs out a bit.
All that being said, and keeping in mind that I have done better and achieved higher scores and rankings with one of my XDm's than any 1911 I have qualified or competed with, I still prefer my 1911 as a daily carry. For me "there is no substitute."
