Im not sure if I understand the question....that is only one of the 2 external safety functions of the weapon, the other is a safety on the backside of the grip.
Both of the safetys must be engaged in order for the weapon to fire.
That is sweet, been wanting to get one of those for sometime
Sweet! I love my XD.40! I have about 4000 rounds thru it. Never has had a problem... My wife went for thr XDsc9....both are great guns. Enjoy it.
To answer your question, that is the trigger safety. Both that safety and the grip safety must be engaged or the weapon will not fire. More commonly called a "drop" safety if I recall. Meaning the weapon cannot fire if dropped. It took me a little getting used to as well.
Nice choice. My first was recently as well. the 3.8 xdm 9. I love it. Saw the 40 was just released too.
I bought an XDM 9mm and really thought it was a nice gun, Never had a problem with it and it shot and cleaned up really nicely..however i was bitten by the Kimber bug and sold it.. I enjoy my Kimbers and they shoot great also... but i do regret selling that XDM 9.. one reason was it was a little too large to carry concealed, but now with the new smaller 3.8 i am thinking of getting another one. Gonna check them out at the gun show this weekend.
Good luck with yours I am sure you will really enjoy it.
Congratulations on your new gun.
I recently bought a XD 9 sc and love it! I too tried several different guns and kept coming back to the xd. I have fired about 250 rounds and it has been flawless. Easy tight groups at 10 yards. To be sure there are prettier guns but I don't think that there are any better for the price. Enjoy.
I'm VERY happy with my XDM40 3.8.
