The light seems great in the limited time I've spent with it. They seem very hard to beat for the price.
I'm excited to take it to the range and test it out. I've had a P07, SP01, and currently own a P10c and they have all shot very well, so I'm expecting the same from the P01.
Compared to some of my other guns, the reset is a bit a long and the DA pull is bit stout, but I'm sure a call to Cajun Gun Works can fix all that.
After buying it, I removed the Glock G43 I was carrying IWB and put on the P01 and I honestly didn't feel a huge difference. Looking at specs, the P01 is roughly 10-12 oz heavier, and maybe quality of the holster I got with it helped offset the extra weight, but that did make me excited to incorporate it into my carry rotation.
