I have a Holosun 407K X2 and want to put it on my PSA Dagger. It is supposed to be a Glock 19 variant. I can not make it fit. What adapter do I need to make it work?

by John

Dear John,

This Toni System Pistol Mount for Glock would fit on the Glock 19. To mount the Holosun 407K X2 on it, you would need to choose "Type A" in the "Size" selection bar.

However, we are not familiar with the PSA Dagger, so we can not be 100% certain that it has the same mounting standard as the Glock 19. We kindly suggest you to contact the gun manufacturer to find out more about the mounting options if you have any doubts.

Please do not hesitate to contact us again if you need any further assistance.

Hello Can i mount the holosun eps red dot to glock 17 mos with this adapter?

Is this for Glock 43X mos? TQ.

by Den

Dear Den,

Thank you for your inquiry. The Glock 43x and 48 MOS truly are slim versions of a standard MOS model. They also do not include standard adapter plates so we are afraid to say that the mentioned adapter from Holosun will not fit. Also, you need to be careful with choosing the correct red dot sight since it needs to be compact enough to fit into the cut. For example, RMSc models have been made specifically for these two Glock MOS models.

Should you require further assistance, please do not hesitate to contact us again.

We are to mount a Holosun 507k onto the S&W shield plus. The Shield plus comes with an optics cut that fits the Shield RMRS footprint so we are looking for an adapter plate to let us mount the Trijicon RMR standard footprint used by Holosun. Do you have an adapter plate that would fit that purpose?

by Prescott

Dear Sir,

thank you for contacting us.

Please note that Holosun 407K and Holosun 507K feature a modification of the Shield footprint. The differences are: 

 - the two rear sockets are missing

 - the sockets in the front are shallower

Meaning if your is optics ready for Shield standard footprint you do not need an additional adapter plate/mount. You can find more information on reflex sight footprints on our blog page here: https://optics-info.com/footprints-on-red-dot-sights/.

Thank you for your understanding.

Will this plate convert a 507c cut to a 407k cut? Thank you.

We kindly apologize for the late reply, which is a result of the increased demand for our services.

Unfortunately, this plate is not designed as a converter. It is suitable for red dot sights that share Shield Sights RMS footprints such as Holosun 407K, and 507K.

Hello, I have a Taurus G3C TORO optic ready pistol. What adapter plate will fit the Holosun 407K?

by Bill

Dear Sir,

thank you for contacting us.

Please note that Holosun 407K shares the footprint of Shield Sights, however, it is a modification.

Holosun 407K and Holosun 507K feature a modification of the Shield footprint. The differences are:

-the two rear sockets are missing
-the sockets in the front are shallower

For this reason, some pistols that are optic ready for Shield footprint need to be modified for the 407 and 507K. Namely, the two rear indexing lugs on the pistol have to be removed and the two front indexing lugs shortened in height. Hellcat and Walther PPS are examples of such pistols (some pistols, such as Sig Sauer P365XL, do not have to be modified).

Please note that you will need to purchase the adapter for your handgun from the manufacturer's store.

Should you require any further assistance, please do not hesitate to contact us again.

Kind Regards,
