Good options for this problem are few and far between. If you're still looking for a holster, you might look a Elite Survival Systems. They make a very adjustable unit that is well made and has many different securing methods...actually too many for me as I cut off one of the backup straps. The holster pictured is their larger version that nicely swallows my G34 & Viridian Gen2. I modified this one to only have a thumb snap strap by permanently attaching the velcro strap at a specific angle...it would normally ride inside the velcro pocket but, the stitched pocket wouldn't allow the angle seen. It also has a spare mag pocket. With a couple minor adjustments this holster will hold the FNH 5.7 & laser just as securely.
