If a little suburban matron like me has carried a 1911A1 for 30 years with no problems, what's to complain about?
If it ain't broke, don't fix it. Sometimes it's just the marketing geniuses trying to promote a product.
You said it.
Years ago, I was one of the very first adopters (first 500) of the SIG P229 in the 357SIG cartridge. I was also one of the very first people to begin hand-loading for it, having obtained one of the first batch of RCBS dies.
Almost 15 years of experience with this cartridge left me very weary of new ones. Short case necks led to bullet setback and two KaBooms! (of minor damage).
While I really liked the power behind the bullet, the case had too many design flaws to continue using it. I’m back to 9mm, .40 and .45ACP for all my pistols.
