Is it a Sig, H&K or other known reliable brand?
Is it accurate?
Are the sights easily visible in the dark?
Is the trigger smooth, not a lot of uptake, quick reset?
How many internal and external safeties and do they block the firing pin if the weapon is dropped? I prefer less or even no external safeties so long as the internal safeties are up to the job?
Does it carry the number of rounds needed?
How does it feel in the hand?
How does it feel on the range?
Is it sufficient caliber?
Lastly will I be embarrassed to be seen with this thing at the range?
