I mean how hard is it to obtain a gun?
Licensing process is still in force at the moment. Rules are very similar to german or
australian, but procedure is a bit more bureaucratized.
Basic algo is:
1. Get a certificate confirming that you're 1) neither drug addict nor alcoholic, 2) not suffering from mental disorders;
2. Buy a gun safe;
3. Pass an exam on rules for safe gun handling. It's not required if you have a hunting license;
4. Local police officer should conduct an inspection of your storage facilities and that you are storing your firearm correctly;
5. Pay a small fee, it's 110 rubles now;
6. Provide a report on the inspection and certificate from the doctors to department of licensing at the local police station;
7. Buy a weapon;
8. Come back to the police department to register your weapon;
9. Now you're happy owner of shotgun.
However it's actually not a problem because you're allowed to get a license even if you were convicted in the past. Entire process usually takes from 4 to 6 weeks.
P.S. Steps 1-4 are required only if you're buying the weapon for the first time.
