Busy week! It started off with two days with Ken Hackathorn, followed by an afternoon as part of Ken’s Ft. Harmar study group, and then finally teaching an Aim Fast, Hit Fast class for a great group of deputies at the Sacramento Sheriff’s Office range facility in California.

The highlight of the week was shooting the Hackathorn Standards with Ken himself running the timer. For all the years I’ve know and shot with Ken, this was the first time I ever shot “The Hack” with him. Turns out that Ken doesn’t use the drill much himself anymore, even when teaching. It was something he developed years ago for a certain military unit and apparently the version that has become popularized on the internet is a bit easier than the original… more on that later this week.

The G17/4 and I turned in a respectable but far from perfect 288. It was my personal best on the drill, though, up three points from a previous best of 285. I missed breaking into 290 by a single strong hand only shot on string 3, which I shot in less than two seconds (par time is 3) instead of taking the time to get my hits. Many swear words were uttered.

Also this week, the G17/4 has been running the first working prototype of the as-yet-unnamed “gadget” that replaces the slide plate on a Glock. As you can see from the photo above, it’s completely integrated with the pistol and won’t even be noticeable past a few feet. You can learn more about the “gadget” at

As for that awesome orange holster, it’s courtesy of the great folks at Cane & Derby. We are working on some final tweaks to their already popular appendix carry holster. Actually, the holster is only orange on this side. The side that faces out remains black to minimize any telltale eye catching signature through light clothing or if a cover garment rides up, etc. I’ve also been using one of their appendix magazine pouches exclusively for the past week and it is working out very well both in terms of concealability and speed.

Train hard & stay safe! ToddG

  2. I’d call it “Tact-Plate” for Tactile Plate. Either way, great invention Todd & Tom.

  3. What’s with the large bulge on the holster, near the muzzle? Does that force the grip and back of the slide in to the body?

  4. Yes.

  5. Thank you for a great class! Your teaching skills and the lessons provided were/are remarkable.

  6. Any chance of sharing what “tweaks” will be made to the Pardus and if they’ll be available? I was about to order one and now considering holding back.

  7. I’ve had my CDI appendix rig for a month now, but haven’t been able to spend any time with it. That bulge raises some concerns, so far theoretical though. It does rotate holster’s mouth into the body, so one might have to point muzzle into a body to find that holster’s mouth. Kind of entirely opposite to Shaggy with its wedge shape that, to me, rotates holster’s mouth away. I’d mentioned it to CDI folks; they haven’t had any issues with it. Has this concerned you to any practical extent, Todd?

  8. also curious about when the changes will be in effect on the Pardus or if it wil be a new model.Definitely will hold off until your tweaks are implemented, please keep us posted

  9. Hey guys, Ian here at CDI.

    I want to address a few things but i will start simple as time is limited right now. The bulge on the back of the holster is contoured to do two things.

    1. It pushes the butt of the pistol where the striker plate (or Un named Gadget) resides into the stomach to prevent excessive printing or canting outward of the pistol if the belt is not cinched up tightly.

    2. It works in conjunction with some other features of the holster body to pull the pistol grip, magazine well end into the body.

    Small tweaks are merely options, such as a comfort layer backing for people that want a little bit of padding in that area etc. There are lots of exciting things coming from us and we genuinely enjoy working with Todd on our designs, his feedback has been marvelous. If anyone has any questions that haven’t been addressed here please do not hesitate to email us or give us a ring! Thanks for the interest guys!

  10. I would think the holster bulge that cants the muzzle out and the butt in for concealment makes for the safer angle to re-holster AIWB. Seems like good design. Assuming no adipose issues. 😉

  11. I’ve been wearing my CDI appendix rig for about a month as well, haven’t had any issues with reholstering. The bulge is very effective at keeping the gun tucked in and not at all uncomfortable. Great holster, very comfortable – I’m very happy with it. Didn’t know CDI had an appendix-specific mag pouch though – must be new?

  12. Cool guys wear orange kydex gear.

  13. Johnny, Glad to hear you’re enjoying the rig! Our Appendix pouch is available but only upon request. We are still ramping up production and debating whether or not we want to offer it for ALL models or just the usual suspects. Email us if you have any questions!

  14. Todd:

    If you can get the “gadget” to work functionally and safely every time, in my opinion you will have turned the “safe-action” pistol into a truely safe weapon.

    I have seen accidental/negligent discharges on re-holstering; they really do happen (and not just with Glocks); they are a very legitimate safety concern and a device that can prevent or reduce their incidence is long overdue. I personally like manual safeties, but a device such as this would eliminate or reduce my concerns. It is potentially a very big step.

    Everyone claims to “think outside the box” these days. It’s nice to see someone actually do it.

  15. Ian:

    Are there mounting options that would make the CDI holster tuckable?


    By iakdrago on Apr 18, 2011

  16. Drago,

    We’ve got attachments in development but prior to their release we want to put them through their respective paces. We hope you understand!
