If the barrel is thick enough and it's a small caliber change to a larger size, it can be done. But it requires specialized barrel milling machinery, and the quality will never be as good as the original caliber it was designed for. Also; you would need to install a different chamber that would handle the larger round, as well as a new magazine. All in all, you're better off just to buy a new gun in the caliber you want.
One can make a pistol much larger than it needs to be, maybe even having an extra-long barrel would make a pistol larger, technically. I'll assume you mean the barrel diameter. Although it would seem that a .380 and .38 would have the same barrel diameter, namely, 38/100th of an inch, that is not usually very accurate. The .380 ACP has an actual barrel diameter of about .35 caliber, or 35/100th of an inch. The .38 Special has a barrel diameter of .357 caliber, or 35.7/100th of an inch. So the .38 Special has an ever so slightly larger diameter.
No. It would requite a larger barrel and then you would have to find a bigger clip to hold the larger pellets. The larger clip would require that the gun be considerably modified. It's not worth it.
You will have to define what "large caliber" means to you and weather the pistol is a revolver, singleshot, blackpowder, rifmfire, centerfire, pinfire, semi-automatic.
The caliber of a Philadelphia derringer with Jukar 054167 Jukar stamped on the barrel is not known. There isn't enough information to determine what the caliber would be. A gun collector would be a good person to ask.
Obviously, it will depend on the caliber of pistol, and the distance between you and the pistol. A person firing a .357 Magnum revolver would be exposed to ABOUT 140 dB.
if the firearms is deemed (discribed) as a pistol then you would need a permit to purchase.
I would require much more info to answer your question.Please start with the fact that I am not aware of any Smith and Wesson serial numbers starting with the letter V.Please include the type of Smith and Wesson you have(revolver,semi-auto pistol),the barrel length,the caliber,how many shot if a pistol,the caliber of your Smith and Wesson etc.I can then start to look and find a answer for you.
