Full Size 45 Extended Mag

[WilsonFlyer]

There's supposed to be a sleeve. I'd contact whoever sold it to you.

And I messed up, although I think we're getting somewhere with the post above.

See that empty space on the left in the plastic sleeve that doesn't rise to the level of the rest of the "sleeve?" That leaves a void at the back of the pistol between that piece of the sleeve and the bottom of the pistol (where the grip-rod/disengage tool stores). That's what I'm talking about.

Here's mine, had to shine a mag light on it to even be able to see that there was a hole, otherwise the shadow just blended in, in the pic and you couldn't even tell it was there... On the 45 take down tool there is a little metal loop which I have always thought was an attachment point for a lanyard like the way Tuco (the Ugly) carried his revolver in "The Good, The Bad and The Ugly". I could be wrong, but I think that little bit of cut away is to allow for that attachment when the extended mag is in.

You're leaving your takedown tool in right? The cutout you see in the side view picture earlier in this post is there as clearance for the take down tool.

Here is my M&P with 3 extended magazines they all look like the very first magazine picture in this thread. I assume they were designed that way. BTW they all perform flawlessly.
