Ive carried a glock 10mm mod 20 for several (3) decades
they are not as accurate as my SMITH & WESSON 1006, OR EAA WITNESS 45 acp
glock groups are about 3" at 25 yards, both the others shoot closer to 2" groups
the glock 20 pistols are marginally lighter and marginally more dependable,
and certainly both of those other pistols have slightly,less mag capacity,
than the glock 20, 15 cartridge , higher magazine capacity,
and the glock 20 requires less periodic maintenance.
I can purchase glock mags for about $20, the other pistol mags run,
$34 for EAA and $80 each for the S&W both hold 9 cartridges
all are certainly up to the job, but theres certainly far more holsters
for glocks available, if I have to use a pistol for self defense,
chances are excellent ranges will be under 20 ft, not yards
