My EDC is a Sig P6 (11-83) that has been worked over by Robert Burke, The Sig Armorer. I also had Mr. Burker fit a EFK Fire Dragon barrel as I want to preserve original barrel. This pistol just fits my grip and sight picture better than my other pistols (Sig P229 manufactured in 2017, and Taurus G3C manufactured in 2022). The pistol is as accurate as I can be. Another "gun expert" associate said I was wrong for depending on such an old gun for my EDC. He said I was putting my life at risk depending on a 40-year-old piece of metal that is probably suffering from fatigue and likely has hidden cracks. I didn't pursue this discussion much as I thought he lacked any validity. Now, I am curious as to whether there is any validity to his position. I can't find any real article on this subject. Is there any validity to this position. This pistol has been examined by a recognized expert armorer who said it is fine.
I've got one as well, it boils down to maintenance, and keeping springs fresh. Just as the recommended replacement interval charts, are just that. Proper use as well, is important, as I have repeatedly brought up, the practice of dropping a cartridge into the chamber, and expecting the Extractor, to "jump" the case rim, which is not how it was designed to work. That's the quickest way to destroy a hard to replace Extractor. Maintaining a tight Breech Block, in the Slide, could help prolong the Slides life as well. This is where I would suggest refrain from using +P, to prevent possible stress fracturing of the early Slides.
Having the later feed ramp replacement Barrel, gives a higher probability of reliable functioning with most effective defensive ammunition.
Of course maintaining your Magazines are also important, thankfully Wolff Gunsprings has replacement Magazine Springs, to keep them functioning.
While it would not be my first choice today, I did use a '97 P225 as my EDC for 18 years, and never felt "undergunned".
