Is chamber pressure a concern when choosing a pistol, or are pistols engineered to withstand, say, for example, 10k rounds without having any adverse wear and tear on components?
According to
Wikipedia, these are some of chamber pressures of a handful of popular calibers--
.45ACP----------21000 psi
9mm & .40S&W--35000 psi
10mm-----------37500 psi
.357SIG---------40000 psi
It could be that a person will never fire enough rounds in normal usage for chamber pressure and the related stresses to ever be a concern. Do any of you guys that shoot regularly ever take it into consideration? Would it be a factor in choosing a caliber?
