I have a rigid mentality when it comes to my firearms and have on occasional gone to extended lengths in keeping with that mindset. I had handled a few SW1911s and shot one example before setting my sights on the new E-Series.
The good: first 500 rounds with zero failures. No brass to the face, no "magazine" related, "ammo" related failures, nothing. Accuracy was very respectable. Trigger was reasonably light with some noticeable creep but in no way unmanageable.
The bad: thumb safety was a bit mushy. Grip safety was trapping the trigger bow due to a rough burr. Barrel was poorly fit resulting in rounded upper lugs. Slide stop showed damage from barrel link (riding the link).
Now S&W offers a great warranty but I ask myself this: would I chance continuing to shoot the pistol to failure in order to enforce my warranty and risk injury or failure or do I fix what is wrong on my own dime? So, new barrel, bushing, plunger tube, slide stop, thumb safety, sear, hammer and disco, fixed the grip safety.
Nearly 3,000 rounds later it is still failure free, accuracy is improved and there is no further evidence of wear on any parts. All controls function smoothly and without issue. Was it overboard? Maybe, but it suits me now and the total price was still far less than many semi-custom offerings.
