Andy,
If you have a Brazilian 1911 from Springfield, it's likely to be a good one and worth the time and attention of a gunsmith; but not just any gunsmith. It has to be somebody thoroughly familiar with the design. Many gunsmiths are.
FNorm,
You have a P7. Truly wonderful, safe, reliable gun; virtually foolproof. I have a P7M13 which I bought new in 1986, but don't shoot much due to the need for jacketed bullets only. I shoot mostly my lead bullet reloads. And the gun is a bit bulky for daily carry, although I designed and made a good holster to carry on the rear of the belt.
And I had just about run out of the bullets I swage for it only, 125 grain truncated cone jacketed soft point hollow point. So the last two days, I made a batch of 420. Then I happily discovered that they feed just fine in my S/42 Luger, also. I'll have to run some through the chrono, when time permits.
So this is a new dilemma. Looks like my Luger might handle my favorite serious bullet, but I can't bring myself to trust any Luger, even one that seems to run reliably, for regular carry when there are other options. Guess I'm getting neurotic, when I have so many choices.
