The Holosun 507K will be available very soon, possibly within the next week or two. The idea of having a carry size pistol such as the P365 and P365XL with the capacity of some duty pistols is very alluring. They become even more alluring when they are optics ready and have the potential to be as reliable as their full size counterparts. Originally, I wasn't sold on the P365XL, but given that the only current competition would be the Glock 48 with a Shield Arms magazine, I'm tempted to pick one up along with a new 507K.
