200
it is a little less powerful but not by much
Put it on a scale
Which .45 handgun are you referring to? The .45 Colt revolver (Peacemaker) goes back to about 1873. The traditional "45 Auto" was adopted by the US Military in 1911, but there were other, earlier .45 caliber automatics. And of course, .45 caliber black powder ball and cap pistols, ball and cap revolvers, etc are MUCH earlier than the Peacemaker. So... which handgun?
10-1000 USD depending on specifics
50-500 usd
15-75 dollars
100-400 USD depending on condition.
To get an answer, you need to provide details like, brand, model, condition, serial number.
You would have to give more information. Exactly what brand, model, caliber, and what condition is it in?
It depends on exactly which model it is. I have a model 1934 Mauser 7.65 pocket pistol that is worth (according to "the book") about $500, however, there are some rare models that are worth much more, some well over $1000, if I remember correctly.
No such model number. Need a detailed description to include caliber/gauge, handgun or longgun, condition and all features.
