BANG!
Depends on who made it.
That is not slang - 40 cal stands for 40 calories, which is a nutrition measurement.
You will have to contact S&W
No such weapon made by S&W
Depends on the model, all have their own virtues however the best value listed is the Springfield armory XD .40 S&W.
no. nor can you fit a 40 cal shell into a 9mm chamber...............
Depends on the load.
10-40 USD
15-40 US dollars
No. 10mm is close to .40 cal, smaller than .50 cal.
my opinion is the 45 ACP round has more knock down powder then the 40 caliber
Maximum range of a .40 cal pistol is about 960 meters. ACCURATE range is about 50 meters.
