No ...... my word ........
All of my handguns / even the oldest revolvers I have from the 1940's thru the 1970's...have all had an exclusive diet of FMJ bullets - mostly Montana Gold ...for many, many years.... with no barrel wear issues.
Many of my handguns have well over 25,000 rds thru them....even the newest one, is about 3 months old now ...and has well over 2,000 rds thru it already - all FMJ.
and I'm not talking about 2 or 3 guns ...I'm talking about at least 25 S&W revolvers, several 1911's and several Sig Sauers...in a variety of calibers...in 9mm, .40S&W, .45 acp, .38 spl, .357 mag and .44 mag..../ no barrel wear issues on my guns ( and they're cleaned - after every range session ...).
