Brulen now days +p & +p+ don’t mean to much. Before reliable hollow points were developed it was the method used to make fmj’s work better. Like most arguments about guns many opinions are based on less then reliable sources. An internet search on BHP brings ample information on wide spread military use, metallurgy and just about anything anyone needs to know about a gun. Most current production guns including Glocks use the BHPP linkless design. One notable gun writer made unsubstantiated comments in 2004 about BHP that are still passed for facts.
A search on Browning BDM brings up many user statements to the effect of 35,000 rounds through guns with no problems.
