Over the years, we occasionally heard from customers the following complaint: “sometimes, when I try to re-holster my gun, the slide lock is down, and I have to lift it manually”. This complaint was almost exclusively from Tanfoglio or Sig shooters.

As it turns out, the issue never was that the slide lock had fallen down, but rather that the edge of the trigger guard on these guns, being steel and often a little sharper than plastic guns, was catching on the upper tooth of the slide lock – rather than sliding past it to engage on the lower tooth, as it should. As a result, the slide lock would move down under the trigger guard, rather than engaging on it, forcing the user to first lift the slide lock all the way up before re-holstering.

This issue is caused because the slide lock is only lifted on the draw as far as it needs to go to release the gun. That means that upper tooth is displaced sideways only as far as was needed – and no more. Not all the way to the upper end of the track.

So – after some trial and error, research and development, we are pleased to offer you the new Magnetic Upgrade option for your Racer or Race-Master holsters.

This system incorporates a pair of powerful magnets, which are positioned to reject each other – creating what feels like a spring-loaded system – and two very distinct positions for the slide lock – all the way down – and ALL the way up.

Now, as the gun is released on the draw – the magnets continue to push the slide lock upwards – higher than the gun itself pulled it – thereby ensuring that when you come to re-holster, there is no chance of catching that upper tooth as you holster.

An additional benefit of this magnetic system is a distinctive “click” which is heard as you holster. Something that is common with other holsters, and requested by some for the Race Master as well.

Note that this Magnetic system replaces the option of the Tension adjustment Knob. It does away with the aluminum wedge and spring as well.


 If you are ordering a holster or an insert block for a CZ TS Czechmate or CZ TS Orange, please see picture of the trigger guard.

New to Competitive Shooting
Very pleased with purchase as it was difficult to find holster to fit Sig 226 X-5. This one works well. The you Tube videos on setup and use were extremely helpful. Customer service was helpful to expedite a return for the proper insert.

DAA Alpha X holster - block insert
Modularity makes the DAA Alpha X block insert for its holster a veritable must have if you are a competitive shooter. Benefits range from it being adaptable, cost efficient, and convenient. I have two holsters but six block inserts- 1911, STI, SPS/Bul, CZ Shadow 2, Cz TSO, & HK USP.
  Across six USPSA shooting divisions, to get holstered quickly and not think about having six holsters; you simply change the insert block in less than one minute.
DAA insert blocks for holsters are well built, ergonomic, safe and hold guns in place securely. An ideal product for novice as well as competitive shooters.
 I recommend DAA Alpha X insert blocks for the DAA Alpha X holster as a 5 star product.

DAA 1911 Race Master Block
A Springfield RO fits loser than other block/gun combinations.
Gun is held securely, but moves more than I'm used to.
