my p7 replaced my r51 back in 1980,like stated the r51 to me had similar pointability as the p7.
the 9mm won out over the 32acp.
i wish i hadn't traded the 51.
bought mine back in 81,paid 319 for it,lots of money back then.
dont shoot lead boolets in it.
i thought they are alot quicker to clean than most anything.
really smooths out the quiicker you pull the trigger.
