What ACP should I get is a question that we get a lot and we are happy to help but you are probably the best judge as to what you need. And if you decide you don’t know, want more than one profile for different guns, or just want to try them all make sure to check out our Combo and Triad packs to save a little cash… 


All of our pillows feature adjustable fill (with the exception of the ACP-FIXED and Mini Mag). The end user can easily adjust the amount of fill in the pillow thanks to an open-top design that is closed with specialized hook and loop tape.


The Pad is our smallest pillow offering and is great for popular carry set-ups like Sub-Compact, 1.5 Stack and Small Single Stack guns. The Pad is flat making it the perfect addition to any AIWB holster if you are looking to increase comfort and reduce hot-spots while adding minimal bulk. The Pad is also recommended for IWB/OWB carry for all sized guns.

The Wedge is designed to work with all AIWB carry set ups and is ideal double stack guns from subcompact to full size. A good choice for use with small, concealed carry type WMLs (Think TLR-SUB size or equivalent). The wedge can be used with minimal fill to add modest cushioning or filled to capacity to achieve significant wedging, and everything in between. The Wedge is our most versatile option is what we recommend if you are unsure of what to get.

The King Size pillow is our second largest size pillow allowing for varying fill levels to create an overall larger pillow wedge. It can be used with minimal fill to add modest cushioning or filled to capacity to achieve significant wedging and grip tuck. The King as the name implies is large; it works particularly well when used with larger concealed carry WML setups (Think TLR-7HLX or equivalent) and ‘Sidecar’ style holsters. It also works well for bigger guys. If you are rocking a power gut the King might make a good substitute for the Wedge.

The Mega Pillow is huge. For years we have had requests to make a pillow larger than the King. It is now here and if you are looking for the largest pillow the Mega is for you. It is meant for full size pistols with duty size WMLs, and Sidecar style holsters with full size pistols/mags/lights. It is also for you if you have a King and want something even bigger!

Approximate Dimensions: L: 5”, W: 5”

The Fixed Pillow is a non-adjustable version of our Wedge. It is best for those that want a general-purpose wedge without needing to adjust fill level. It offers a one size fits most, providing a good balance of comfort and concealment.

The Mini Mag Pillow is also non-adjustable and is designed specifically for small gear like magazine carriers, sheaths, and the like. It is a mini version of our Pad; it primarily adds comfort with minimal bulk. It does not offer significant grip tuck.

Red hook covers are provided to keep the hook-and-loop hem clean when filling and/or adjusting fill level. use them like a funnel to help get the fill in and keep the hook and loop clean. A marker, pen, or similar is helpful in getting the fill down to the bottom of the pillow. Remove the red covers and you are good to go.
