The only semi-auto US pistol mfr to win Olympic Gold was High Standard, back in the 20th century.
No US mfr has done it since.
Gimme an old High Standard from the 1930's-80's, especially the Hamden Olympics...it'll shoot more precisely than any new US-made pistol.
That being said, unless you are a highly trained shooter, 99% of good quality pistols out there are capable of better precision than you are.
So...Practice, Practice, Practice...just like an Olympic Pistoleer...and in time you can wring accuracy out of even the worst pistol
by using consistant and precise hand movements, having additional hand and arm strength, & with using proper stances.
