Like the OWB version, these Ff12 IWB tuckable holsters get that name from the two main panel sides. Mirror image left and right panels join along the center line of the firearm. Each main piece forms half, or 50 percent, of the primary structure of the holster, hence the term 5050. Standard cant (angle) is 15 degrees forward tilt. Customization is available.
Ff12 IWB tuckable 5050 panel holsters are similar in construction to the curved panel holster in that both have forward and rear belt slots. Because they must fit the curve of the body, this mirror image construction is more susceptible to binding than curved panel holsters, particularly for slimmer wearers. This is discussed further in a blog post. They seem better suited to revolvers and smaller automatics than to larger pistols. In a few cases cases, these might be recommended (the Bond Arms Bullpup 9 is one of these).
Like the curved panel models, these have an added reinforcement panel in cowhide or select exotic leathers. In the Ff12 style this reinforcement piece wraps around, reinforcing the entire holster mouth as well as the sweat guard.
Because of the tendency of the 5050 “pancake”to bind, the curved panel holsters must be considered the upgrade. Still, we continue to make these due to their widespread use. You can order the 5050 holster, but we nearly always recommend the curved panel.
