Ppistol used by Shri Chandra Shekhar Azad
The last time I visited the Allahabad museum i was relieved to see the Colt pistol and all doubts silenced.
It is a Colt Model 1903 Pocket Hammerless semi-auto pistol in .32 ACP caliber. It is a single-action blowback pistol with a 8-round detachable box magazine. Effective range would be 25-30 yards or so.
