I have a cz p10f stock and a gucci g19 comp'd really good product, will be buying a surefire version as well
Satisfied with my purchased just wish the holster was stricter designated for the X300b light and not both.
I have a Shadow Systems MR920 with a Streamlight and a compensator which fits absolutely perfect and just the right amount of tension. Highly recommend.
Great holster even cover's my g17 with a arc sparc comp
