I stopped buying Fobus holsters after they exceeded the $16 mark.
For what it is, it was (past tense) a functional, economical, serviceable holster at its price point when synthetic molded holsters became "in vogue" for pistoleros.
Since Galco, UNcle Mike's, and a slew of other manufacturers came across injection molded Kydex, the price points at $20 became the standard for polymer shell holsters which are tougher, and better finished. This beat out Blade-Tech and Comp Tac's monopoly on $70+ Kydex holsters.
Now, Side-Armor and a couple of other recent additions like C-Tac make some really nice Kydex holsters and they are worth the dollars. DeSantis came out with their $30-35 price-point Kydex rigs which are also very nicely fitted and formed to the specific guns. Better than Uncle Mike's.
Fobus was cheap in the late 90s, because the Israelis made it out of PVC. It is the same stuff as roof gutters, lawn edge hedging material, or drain pipes for rain gutters. The rivets were an economical solution to assemble it. It was not really glued or thermo-welded. Imagine a soda pop container cut out for the flat portion of the material, flipped over, stapled, and heated to form the shape, and it was pretty danred close.
I am actually happy with the ones I have for the Glocks in 26, 23, 20, Beretta 92, and even the 1911.
They are disposable. If one cleans the inside with a wet paper towel from time to time before holstering, it keeps the grit from scratching the finish. PVC is soft, and gouges very easily. I see evidence on my hard-use 1911 holster. A little Armor-All on a wet towel inside the holster helps prevent static and lubes it a little. Silicone will attract more dirt.
These days, they are made in ankle, swivel, retention, etc. This is where they took a good thing and ruined it. PVC is limited in stiffness, with the current thickness gauge FObus is using. It is cheap. Vacuum forming is fast and cheap. The paddle tears off with hard use.
These days, a handgun owner has better options in the price range of $20, and the true Kydex materials can be had.
My preference for economical Kydex is the DeSantis offerings (Nitewatch, etc.). I know what is means to not have a lot of discretionary income, and one wants the best option available.
These days, Fobus is not the best option for the money. Your best bet is to raom the gun shows and gun shops in the used bins, and find a decent turn-in FObus for around $10, and try it out. This way, you do not lose anything, except one or 2 day's lunch money at a fast food restaurant.
