Hey everyone I'm new here but definitely not new to shooting guns. Anyways my 21st bday is in exactly one month (yay me!!!) And I'm purchasing my first handgun for my birthday. It's between the m&p and xd. I will eventually be carrying either one once my ltch comes in the mail (hopefully soon but Im sure I'm in the bad boy pile). So my question is is it safe to carry IWB with nothing other then a trigger safety cause I'm leaning heavily towards the m&p without the external safety. But it just worries me that there Isnt a safety other then the trigger. Which is why I'm considering the xd because of the fact it has the thumb safety.
