do not just go off and shoot
I knew NOTHING before I shot a pistol during my nra safety course.. Then the fire was light. I went to the range and shot .22lr and 9mm(9mm luger=9x19) full metal jacket(fmj) ammo. I had to wait 3months for a permit so I practiced on a range that allowed nra safety certificate holders to shoot.
So practice a lot and do it right each and every time-
Concentrate not just on your grip,stance,trigger movement... also ingrain the top safety rules into your habits
read perfect pistol shot--blog and book on amazon
watch youtube video about your gun, watch others shoot it on line. check out the following vidos" ultimate pistol grip" and thumbs forward grip" for a start. take lessons ,ask ? of us and all who will listen.
if you do not feel safe--you are NOT--take lessons or take the nra courses offered on ranges near you
the basic safety rules are only a start--there is so much more. CCW is a responsibility not just a right. Take it seriously,prepare,train
get a dry fire air pistol like your xdm and dry fire until your finger hurts--
most of all welcome and enjoy safe shooting
