Perfect and snug fit for my new BUL SAS II TAC5" pistol. The pistol is held securily and can subsequently be unholstered rapidly and freely. Top quality accessory from Double Alpha Academy. Good job

I have a Gen 3 Glock 34, must need filing using a dremel. Make sure you follow what the video instruction says and be patient. You also need a pencil to serve as a marker so that you do not over file it. Be careful not to over file it otherwise you won't be able to use it anymore or it will be...

Before purchasing I called to make sure this would fit the NEW model p226 x5. I was told that it would fit the made in the US p226 x5. When I received the alpha-x insert block I spent several hours trying to make it work but was unsuccessful. I then called back again to tell them about all the...

Ordered the Glock version and I did have to trim to fit (Glock 17 Gen 5 MOS).
However the video shows you exactly what to do and was done in 10 minutes.
Very nice fit now.

Requires filing the retention cut out (spot that hooks the front of your trigger guard) or it will fight you on the draw (specific to atlas nemesis). Outside of that it’s great

Bought is it for SVI steel grip. As usual great quality. Needed a little modification for a perfect fit. This is exactly as i expected as no gun is alike. Therefore it is nice to have it al little oversized so you can make it fit exactly as you want.

Alpha-X / Race Master Insert Block

(127)
Manufacturers: Double-Alpha Academy

Description:

PLEASE NOTE: If you are ordering a holster or an insert block for a CZ TS Czechmate or CZ TS Orange, please contact us first with a picture of your trigger guard area. CZ seem to be using two styles of frames for these pistols ,and without seeing your gun, we will not know which insert model you need. More details here: Click here for more details.

US Patent No. 8720754.

View insert Block pistol compatibility: click here.

The Alpha-X and the Race Master Holsters utilizes 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.

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

 

CRITICAL SAFETY WARNING

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.

You also need a pencil to serve as a marker so that you do not over file it. Be careful not to over file it otherwise you won't be able to use it anymore or it will be loose. Other than that it works perfectly fine with my glock 34.

I have the Bul Armory SAS II with (steel grip) and the DAA Alpha insert fits and works perfectly. Previously I have used the SV and even tried the STI insert for the Bul SAS but wasn’t completely satisfied, when my hip was canted to the side the gun would get caught and I would have a slower draw. Now with the Bul Insert the gun releases quicker, no hang ups at an angle for those fast exits and I have a faster draw time for USPSA open division.
