    The Alpha X and Race Master Holsters utilise an efficient and easy system to allow shooters to switch their holster from one gun type to another by means of changing the Insert Block Assembly.

    This switch is fast and easy and can be done in less than a minute, and without losing any of the holster's adjustments or settings.

    We proudly support the full Double Alpha Product range to bring our UK based customers same day dispatch from within the UK or click & collect from us in South East Hampshire; all UK import taxes are paid by us so the price you see is the final price .... no nasty surprises from UPS !!

    We also bring the full DAA range to the UK's best Gun Shows and most practical matches.

    The DAA Race Master was discontinued some years ago but as they are such a strong unit there are many still in faithful service - I still have mine from World Shoot 2014 !

    The Insert Block Assembly includes:
    1. The Locking Block (gun specific).
    2. The Sliding Lock, assembled (gun specific).
    3. The safety lever, assembled.
    4. The internal magnetic activation system, assembled.

    The Insert block grips the pistol only on the front end of the trigger guard, and a very precise fit is required in that area. In some cases some light modifications to the Insert Block may be required.

    Should you need to dismantle your insert block for some fitting, follow these steps:
    1. Remove the insert block from the holster by removing the two small M4 screws from the back of the holster.
    2. Using a punch and hammer, push the two steel pins from the front of the block towards the back (push from the side with the gun type engraved). These pins may be tight.
    3. Once the pins are out, the plastic wedge holding the 2nd magnet will come out. Make sure the magnet does not fall out the part. It is usually held snugly it its pocket.
    4. Use a marker to make a dot on the top of the magnet which is embedded in the slide lock. This will make it easy for you to ensure that you reassemble it with the correct side up. Most likely it will fall out or you will want to remove it while fitting the slide lock.
    5. To remove the slide lock from the block, unscrew the M3 screw visible from the back of the block – and then slide the slide lock upwards and out through the window in the block – passed the safety lever, which must be in the unlocked position.

    To reassemble - reverse your steps.

    The Race-Master Holster Insert Blocks are design to be used in either RH or LH holsters. The same insert works for both.

    US Patent No. 8720754.

    Note: Both the Race Master and the Alpha-X holsters use the same insert blocks.


    Read the following instructions carefully before using this holster or Insert Block:

    • Never holster a loaded firearm without first engaging its safety.
    • Check periodically to ensure your safety is functioning correctly.
    • Never disengage the safety of the firearm until well clear of the holster and the muzzle is pointing down range.
    • Make sure you are fully familiar with the correct use, and adjustment of your DAA Holster before attempting to use it with a loaded firearm.
    • Make sure that you have the correct holster/Insert model for your type of firearm.
    • Do not use a holster that is unsuited to your firearm, as that could result in unreliable retention or release which could lead to a fatal accident.
    • Never use a trigger shoe or a widened trigger with this holster.
    • Double check that the retention and release work well, particularly if any modifications have been made to your firearm.
    • Care must be taken to ensure the gun is placed properly when returned to the holster. It if it is not positioned correctly, it will not be held securely and may fall out.
    • Never holster the gun quickly or with force, as that increases the chance of making contact with the trigger.
    • Any adjustment or modification to the holster design may render it unsafe or cause malfunction.
    • Take care that the firearm is not dislodged or knocked when holstered, particularly when the holster’s safety lever is unlocked. As this holster has no muzzle support, take care that the muzzle of the gun is not bumped upwards, as this may dislodge the gun from the holster
    • Keep your fingers well clear of the trigger when holstering and drawing the firearm.
    • The holster should be locked when running or jumping with a holstered gun, or you should keep your hand on the gun’s grip to prevent it accidentally falling.
    • Handling a loaded firearm, and drawing it from a holster is inherently dangerous. You do so entirely at your own risk and responsibility.  
    • Liability is limited only to the replacement of this holster or parts thereof. No additional warranties are expressed or implied by the manufacturer or the distributors.

    NOT Compatible with Racer-X or Flex Holsters 

    Safety Note for some revolvers with Target Triggers or Trigger Shoes - DO NOT USE THIS PRODUCT - the wide trigger will function when inserted. 

    ALWAYS check your holster with an unloaded gun before use. 

    Undertake a thorough evaluation to confirm this system is safe to use with your chosen firearm especially if you have any non-standard modifications.
