I mentioned something about this before, but here is a weapon comparison between real modern weapons and mass effect weapons.
Specifically Anti Material Rifles, light pistols and heavy pistols.
AMR (Anti material rifle) Comparison
Barrett M82 AMR (and its variants)
The Barrett is an Anti Material Rifle, capable of firing .50 Cal armor piercing / explosive rounds.
Fire Mode: Semi automatic.
Number of rounds in magazine: 10.
M-98 Widow Anti Material Rifle & Javelin
The widow and Javelin are both anti-material rifles and share the top spot (for SR) for the amount of damage they can inflict in a single shot.
Fire mode: Both rifles need to be reloaded after every single shot. In addition, the shooter is limited to carrying less than 10 rounds of ammunition.
(I'm aware of the concept of game mechanics, but, really? That broke my suspension of disbelief So. Hard.)
Number of rounds in magazine: 1.
Conclusion:
Mass Effect AMR's suck.
Other ME sniper rifles has for some inexplicable reason a bolt that needs to be operated after each shot...
I'm talking about sniper rifles that has a magnetic rail inside them and should have more in common with a high-tech scientific tool than with WW2 era sniper rifles.
"Service Pistol" comparison
M-3 Predator Heavy Pistol
The Predator is a reliable if not amazing handgun, calling it a "heavy pistol" is somewhat of a stretch.
Fire Mode: Semi Automatic.
Number of rounds in magazine: 15.
Baretta 92FS & Glock 19 / 17
Both guns are very reliable, and see heavy use in the US military and law enforcement agencies. They fire 9mm rounds.
Fire Mode: Semi Automatic.
Number of rounds in magazine: 15.
Conclusion:
Am I supposed to buy that space guns made of phlobontium are still in the same level of effectiveness as guns made in the distant past?
ME service pistols suck.
Heavy Pistol Comparison
M-6 Carnifex Heavy Pistol
The Carnifex is a relatively hard hitting heavy pistol, less powerful than the Paladin, and slower to fire than lighter pistols like the Predator.
Fire Mode: Semi automatic. (slow)
Number of rounds in magazine: 6.
M-77 Paladin Heavy Pistol
The paladin is the most damaging standard pistol in ME3, or at least among the most damaging.
It is also a weird hybrid between a pocket pistol made for concealment, and the most heavy hitting hand cannon aside from the single-shot executioner.
(which makes very little sense)
Fire Mode: Semi Automatic.
Number of rounds in magazine: 3.
IMI Desert Eagle
The Desert Eagle is the most powerful semi automatic non-revolver handgun in the world.
Fire Mod: Semi Automatic.
Number of rounds in magazine: 7-9 depends on the ammo used.
Smith & Wesson Model 500
The S&W 500 is the most powerful production revolver in the world.
Fire Mod: Single Action / Double Action. (essentially Semi Automatic.)
Number of rounds in cylinder: 5.
Conclusion:
ME heavy pistols suck. They have less ammo, and shoot slower.
To summarize: 250 years in the future, aliens and alien technologies have been discovered. Chemical propellent based weapons were replaced by railguns. But the overall effectiveness and reliability of weapons seems either worse, or unchanged.
That, makes no sense whatsoever.
