Yes, you can. To be deductible, a business expense must be both ordinary and necessary. So, if your sidearm is ordinary (common and accepted in your trade or business) and necessary (helpful and appropriate for your trade or business) you can claim it.
An expense does not have to be indispensable to be considered necessary.
Note that Employment Expenses are itemized deductions limited to only those over 2% of your AGI.
