The caliber is not identified but the barrel diameter appears to be .32. Other than inserting various caliber casings, is there any way to determine the caliber? 3.) Any idea as to the approximate value of the pistol? Finally, 4.) Is it safe to use modern ammunition? Thank you for your assistance.
Welcome to TFF.
Whether a .32 or .38, it was made in 1911, and all of Iver Johnson's U. S. Revolver Co. guns were made for modern smokeless powder ammo.
The chambers of a .32 will measure about 5/16" diameter, a .38 about 3/8"
Correct .32 ammo is .32 S&W. Do not use .32 ACP, which will also chamber.
You can order grips here, but they will cost about a third of what your gun is probably worth, and will not significally increase the value of it (measure to be sure they are right size):
