For one thing, the maximum bullet size listed in the drawings is 0.3555" in diameter. Think of it as a peg.
Will a 0.3555" peg fit in a 0.354" hole? The answer is "Not easily"
Why have you never heard of this problem? Because the major manufactures of defensive firearms are not stupid. The SAAMI chambers are MINIMUM allowable chambers. The majors bore the throat a little bit long and a little bit larger diameter. Consequently, a Glock or an S&W will feed and fire a wide range of ammo without a hiccup.
One of the neighbors came over with a new handgun. We have a large pit we use for the purpose of test firing handguns.
The firearm was a Taurus G2. It fed the FMJ ammo just fine.
It coughed up a hairball on the 9mm hollow-points. I pulled out a digital caliper and the COAL was 1.125" which complies with SAAMI specs.
So the neighbor's handgun either has a bur in the chamber, machining marks or it is at a true, SAAMI minimum.
Can any of my readers advise regarding difficulty of polishing the throat of the chamber? Are there inexpensive tools (like pencil eraser and jeweler's rouge) that will work?
I cannot imagine that I will need to polish out more than 0.002" to make this a happy-happy gun.
I don't want to tell the neighbor to send the gun back to Taurus. The chamber is probably within spec.
