Shawn both brand names of ammo mentioned are really third rate bullets period. I have been shooting well over 50 years now and can vouch that they are extremely dirty and unreliable for the most part period. I am also used to shooting CCI-SV which is extremely reliable in my m41 and m46. I have owned many brands of pistols and many different models as well. Good ammo is important for any GOOD Gun.Its half of the equation to shooting properly. The firearm is the other half.
