I shot plated Winchester .22LR rounds through the first barrel, and it had heavy lead deposits at the end of the second magazine (32 rounds). The second barrel had heavy lead deposits after the 32nd round as well. The third barrel has the same horrible chattering in the bore as the first two barrels, of which I have posted images previously in this thread. This is not hearing an issue with the TX22’s bore; this is evidence of an issue with the TX22’s bore. With luck, I will shoot the third barrel tomorrow and will report here. I think that the probability of three barrels, all poorly rifled, on a pistol bought in May 2019, indicates that there is a problem at Taurus. Other than for poor quality control, I cannot think of a reason for letting these barrels out of the factory. This is a simple visual inspection: batch inspection, by quality control, should have caught the problem.
As for Kimber, for the past three NRA Annual Conventions, I have been a firearm examiner, ensuring that exhibit firearms are deactivated (will not fire a round). Kimber's quality leaves much desired, for the listed MSRP.
As a Glock Advanced Armorer, brass can fly back onto the shooter, when the pistol is held poorly, which is usually the case, or when a shooter takes a .40 S&W Glock and sticks a 9mm barrel on it (I have seen that), or converts a .357 Sig Glock to a .40 S&W and vice versa. Firearm owners do many foolish things with firearms: firearms are not Legos or erector sets.
As for broken firing pins, the energy of a firing pin is designed to sufficiently indent a primer with enough poundage and distance to ignite the primer. When a firing pin does not hit a primer, the energy goes somewhere else, and, usually, back into the firing pin when it does hit the inside of the bolt, stops, or barrel (rimfire). Thus, they break when dry firing, or damage something else. Firing pins, for the most part, are not designed to be repeatedly dry fired. Though many firing pins can take the punishment, continued dry firing is seldom recommended.
Since I am on a soapbox, Remington lost my business. I sold my Rem 700 rifles, due to the receivers: not square, threads cut off center, threads cut slanted to the center, threads cut with varying depth, triggers breaking. I bought a Rem 783, in .223 Rem. It was advertised to have a 1:9 twist barrel. It had a 1:14 twist barrel on it, which is the advertised barrel twist for the 22-250 rifle. When I called Remington customer service about this, the man stated, “You could shoot lighter bullets”. Instead of address the issue of correcting a factory error, the first thing he offered was that I could shoot lighter bullets. I sent it back, and it came back with the correct twist barrel, and it shot extremely well, but would not eject spent cases from the receiver. The cases would be pulled from the chamber, and then dropped on top of the magazine. After the FOURTH extractor, it reliably threw spent brass. I have since sold the rifle, explaining the problems that this rifle has had. I am done with Remington.
A company either has high quality standards, or it does not.
