Well Safariland doesn't make a P30L holster, but it does make a HK45 with Surefire X300 holster. Until now I've been using it for a S&W M&P 9 Pro, but I finally received my P30LS V1 this week. The good news is that the the P30LS fits quite well. The only problem is the gap between the gun and the hood, which was designed to accommodate the HK45 DA/SA locked and cocked. The gun might slide up and down a bit, but it's secure and cannot fall out. It still takes a lot to make the gun move up and down.
I'm just glad to have one holster to run my two handguns without having to mess with my belt setup.
