you can get the XDM 3.8 Compact with the smaller case and less assesories that includes 2 magazines, gun lock, brush, extra fiber optic sites, 3 extra back plates. $515.00
Oh and stainless steel DOESN'T rust so it must be the black versions. The finish Ive heard comes off of other guns that use that same one. Stainless will tarniah but thats not the same as rysting and is far easier to remove back to a high luster.
I have the XDm .45 4.5 and XDs .45 3.3 with all the same accessories you have in yours and I love it. My dealer tossed in an extra 13 round magazine for the XDm amd I got three extra mags for the XDs through the Gear Up giveaway. Both the XDs and XDm are part of my EDC.
A couple of corrections: 1. It does comebib .45ACP not just .40 S&W and 9mm. 2. Its not a "lanyard" it is a roll pin for changing out the backstraps. I suppose you could use it for that although I wouldn't.
If firing pin sear breakes off while it on cocked position, firing pin block will not stop firing pin to hit the primer of cartrige. Firing pin block should be in the middle or front of the pin like Glock. Not safe to carry.
