Dave85,
There are no professional gunsmiths in India! There may have been a few during the early years after Independence (1947), remains of the British Empire....but none that are present now. The conversion was done very likely in England itself, also I forgot to mention it has only the factory standard rear notch fixed sights and no adjustable sights which puts the target conversion to rest. The other thing was Webley made the Mk IVs in .32 S&W Long.(same as .32 Colt New Police) and not .32 S&W.
Jim Watson,
That is partially correct. Here in India the problem is that there is a military caliber prohibition on civilian firearms. That means just like Italy, and some South American countries we are not allowed to use anything the military/police use. Calibres designated as "prohibited bores" are:
9mm Pistol,.380 Revolver,.45 Pistol,.455 Revolver, .303 Rifle, 7.62mm Rifle. Ammunition for civilian use must not be "cable of being chambered or fired" in Prohibited Bore firearms.
You have to remember that the restriction is on the bore of the firearm and not the exact caliber. That means any 9mm pistol cartridge whether 9mm Bayard or 9mm Kurtz,9mm Glisenti or any other 9mm is a "prohibited bore".Funnily .380 pistol cartridge is allowed.The trick is that the pistol must not be marked as 9mm anywhere but can have .380.
When a license is requested for a firearm, you also mention that you want a N.P Bore(Non prohibited bore) pistol, or revolver or rifle or shotgun. That means .32 N.P bore revolver allows you to buy .32 S&W,.32 S&W Long, .32 H&R Mag,.32-20,or even a bottleneck wildcat cartridge if it fire a .32 bore projectile. Similarly, .30 N.P Bore pistol would allow you to own .30 Luger, .30 Mauser, .30 Borchardt,.30 Carbine etc. Calibres commonly allowed are .22,.25,.30,.32,.38(pistol). I know some have permission for .357 Magnums etc.
Indian ammunition is only available in .32 S&W, .32 S&W Long for revolvers,.32 ACP for pistols, .315/8mm, 30-06 for rifles and 12 gauge shotgun shells. So most people prefer firearms in these "bores".
Ammo for the rest of the bores is all imported and very expensive.
.32 local ammo Rs.35=$ 0.70/round
.32 imported ammo Rs.150=$ 3.00/round
Since shooting is an elitist sport here in India only the rich people can afford to do any amount of shooting or else you have to be in the Police or the Military to be able to get any practice for real competition.
