Will this fit the Beretta APX A1 compact?

Hi William and welcome. Not directly, you will need the RMSc Optics Plate: https://www.beretta.com/en-us/product/beretta-apx-a1-carry-red-dot-optic-plate-kit--holosun-k-series-footprint-EUS03063?srsltid=AfmBOoo9HXYmC3c5zpbJQyxu-Afv_tdngVa3H6fkJtCC5t2WXQtsvFGd ------------------------- Cheers and stay safe!

you will need a adapter plate which you can get from berreta here https://www.beretta.com/en-us/product/beretta-apx-a1-carry-red-dot-optic-plate-kit--holosun-k-series-footprint-EUS03063

Good evening to you!! Yes, the Holosun HE407K-GR X2 will fit the Beretta APX A1 Compact. It uses the Holosun "K" footprint, which is compatible with the RMSc footprint, and Beretta offers an adapter plate specifically for mounting Holosun K-series optics on the APX A1 Carry and Compact. Hope this helps. Have a good rest of your day.

WILL THE HOLOSUM 407K FIT P320 SIG 9MM

The Sig p320 is cut for the pro optic footprint. You'd need mounting plates since this has a Holosun footprint.

Hi Anthony and welcome. You will need an Optics Plate. Optics Plate and Red Dot fitment guide for the P320 is here: https://freedomgorilla.com/blogs/news/best-sig-p320-holosun-optics-adapter-filler-plates?srsltid=AfmBOopT4xRafTTbeOSX5n1NOoD6tUE3jxUR4CvT-jqGjnOUeIFLB9Gh

Does this have a 507k/RMSc footprint? Thanks!

Hi and welcome. Yes Sir, this has the RMSc Optics Footprint. Cheers and stay safe!

Will this fit a Springfield Hellcat? Looking to purchase and want to verify fitment.

Hi Jacob and welcome. Not without an adapter plate or grinding two indexing lugs. Details under Holosun 407k/507k here: https://www.gunsholstersandgear.com/2020/08/01/what-optics-will-fit-the-springfield-armory-hellcat/

it will need a adapter plate or the slide needs to be modified "While the mounting screws are in the same place as a standard RMSc footprint optic, the Holosun sights are not 100% compatible with RMSc-type slide cuts. For reasons that escape me, Holosun did not mill the bottom of the 407K or 507K to accommodate the indexing lugs that are found on the Springfield Hellcat. To mount the Holosun sights, you have two options. The first is to permanently alter your pistol slide by grinding down the lugs. There are companies that offer this service for about $75-100. The second option is to purchase an adaptor plate. An adaptor will allow you to mount the Holosun without machine work on your slide. C&H Precision Slide offers a plate for $45. An adaptor will add a small amount of height and weight to the optic."

C'mon... It's the Holosun 407. There's a reason it's the biggest player in the game. The quality is there and it fits perfectly on my X-Macro and my S&P 5.7 with no annoying plate requirements.
