To load a handgun you need to push the charged magazine into the grip:

Loading a handgun requires careful handling to ensure safety and proper function. The correct approach to inserting a magazine involves firmly and securely pushing the charged magazine into the grip of the handgun until you feel it seat properly into place. This ensures that the magazine is engaged correctly and that the firearm can operate safely.

While it's important to ensure that the magazine is inserted completely, doing so "rudely" or with excessive force can lead to damage or misalignment, compromising safety. Therefore, the key is to apply a degree of force that ensures the magazine clicks into position effectively while avoiding any rough handling that could harm the gun or the magazine itself.

A softer approach might not ensure that the magazine seats properly and could lead to issues such as a failure to feed. Speed is also a consideration; however, a fast insertion without control can result in accidents or mechanical problems.

Proper technique involves a balanced approach: inserting the magazine firmly enough to ensure it is securely in place, but not so roughly that it risks damaging the firearm or causing an unsafe situation.
