Transitioning to handgun in a stoppage.

My experience is...Transition to handgun works and is still a practised SOP but only to be used if you are in a close quarter gunfight. If the bad guys are beyond the effective range of the handgun then drop down or move to cover and fix the stoppage on your primary weapon (while communicating to your team, 'stoppage' or 'changing mags'). Bearing in mind a long gun smashes a handgun in accuracy and effectiveness so your primary weapon gets all the love. If you don't practise to make this fast and smooth then probably best not to carry a handgun.
