I'm super excited to introduce these P365 XMacro backstraps! These backstraps are 3D printed right here in New Hampshire using PLA-CF (Carbon Fiber Reinforced PLA). In most regions of the United States the heat deflection temperature of PLA-CF will be more than enough. However if you happen to live in a hotter southwestern region and/or you leave your firearm secured inside a vehicle where temperatures can reach between 130 to 172 degrees on a 100 degree day we do not recommend using this backstrap. 
 
Heat deflection temperature (HDT) refers to a polymer's ability to remain rigid or “stiff” under a constant load and elevated temperatures. It indicates at what temperature a polymer starts to “soften” under a fixed load.
PLA-CF = 131.0 F
 
I personally use the PLA-CF backstrap and have been completely happy with it. The hatch design with the diamond edges is a significant stippling improvement. Much more grippy but not too grippy that it’s going to chew up your hands during those extended range sessions. My 365 now fits much better and my recent range sessions reflect that as my 365 fits much better now. I'm using the XL backstrap which is significantly bigger than the factory large backstrap. I feel the overall design also makes the factory grip look much more finished. Let me know what you think!!
