We have tried most of the handgun molds that are being sold to holster makers. It has been our experience that each brand has its own issues or set of problems. Most of the holster mold companies have lacked consistency and had quality control problems with the molds we have purchased. For example, some molds have had voids, rough spots, wavy slides, out of spec dimensions, extended slide safeties on this order, and the next order for the same exact split mold would not have the extended safety. Some makers put sight channel blocking that will allow for the use of suppressor height sights and others do not causing us to have to cut the sight blocking off and replace it with our own. Some have had some features blocked on the mold but not blocked others that should have been blocked. While we have not been satisfied really with any of them and have resorted to making our own molds, when we do purchase molds, we prefer the DIY Holsters molding drones because the molds are cleaner and have been in spec. However, we dislike the their blocking for the sights as they do not allow the use of taller suppressor sights. We have to cut that off and replace it which can be difficult. They also ship their orders very quickly which we really like. For flashlight molds, we recommend just buying the real flashlight or contacting the manufacturer to see if they have spare bodies or defective lights they will sell you. The flashlight molds we have purchased have been disappointing and usually will break from the amount of pressure applied in the vacuum formers. Some places are now making the split molds from High Density Polyethylene or HDPE. While we have not used these molds ourselves, we have used a lot of HDPE and found that after being machined and exposed to repeated heat, it tends to warp. We strongly prefer aluminum split molds and consider them superior but they can be rather pricey. Regardless of which molds you use, we recommend always checking the fit of the holster with the actual firearm and not relying on the mold to be correct as they seldom are. You may have to cover your molds with layers of tape to ultimately achieve the correct thickness.
