Race Master/Alpha-X Insert Block Assembly

The Race Master Holster 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 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.
