I like my 1911 style pistols to work well right from the beginning. Clean, inspect, lubricate and then off to the range. I don't scrimp on the quality of magazines and ammunition when becoming familiar with a gun, either. I look at 'breaking in' a new 1911 (or any handgun) to be a mutual experience (the gun and myself) and I don't want potential magazine or ammunition issues to cloud the experience if they can be avoided. Sometimes magazine issues may surface and have to be identified, though.
My SW1911SC 5" (before they discontinued the plain stainless finish SC's) did very well right from the very first range session, and after I made a slight adjustment to the front sight it do so very accurately. I let a die-hard Colt Model O Pistol owner & user try my SW1911SC and he was very surprised and impressed with the accuracy, even when comparing it against a Colt Gunsite Pistol (CGP model, not a GSP) and a Wilson CQB.
I have successfully used the ACT-MAG's which came with it, the previous version of the Tripp-Research Cobramag and some 7-round Colt magazines (which arrived as 8-rd magazines, upon which I replaced the split-leaf followers and light springs with standard dimpled followers and 11LB Wolff springs). I used a variety of hollowpoint duty-type rounds and some assorted FMJ.
The S&W warranty is another point in favor of the SW1911. A manufacturer offering pre-paid insured shipping both ways can make warranty service more affordable for folks.
I'd be willing to buy another SW1911 (and the new SW1911 .45ACP Sub Compact - Pro Series 3" model has been attracting my attention, even though I really don't
need another 1911 to add to my collection
).
I'd also be willing to buy a Colt.
I have seen a few Springfield's I'd be willing to use my own money to buy, too, but somehow just never got around to doing so.
External extractor? Not an issue to me. S&W has been using them since back around '52 and they seem to have benefited from their accumulated experience. Yes, the SW1911 extractor is technically considered a fitted part. There's a bar gauge used to check fit in an individual slide and the extractor has an adjustment pad which can be filed, and last time I looked there was an optional extractor spring available. The Pro-series model seems to use the larger Performance Center extractor design, too.
I've seen used, as well as personally handled and used, a number of 1911-style pistols over the years.
I'm not a believer in brand names for the sake of supporting certain brand names, or having something which exhibits the most currently popular appearance or 'market appeal'.
I prefer to have reliable service-grade guns which are 'practical' versus 'fashionable' and I feel 'function' is more important than 'appearance'.
I have no need (or desire) to spend $2K or more on a 'working' 1911 and I'd prefer to spend closer to $1000 for one ready-to-go.
Then again, I'm not a competitor or avid collector.
However, I do know folks who feel they must carry the very best 1911 available and think nothing of dropping $3K (or more) on a carry 1911 as produced by one of the well known names in the business.
Bottom line? I've been very pleased with my SW1911 and I'd be willing to buy another one.
I happen to like my M&P 45 more, though.
