Grant,
I have to respectfully disagree. I don’t think that the problem with belt loops breaking is easy enough to diagnose as using Kydex as the material. There are a lot of things that influence if belt loops - or holsters for that matter - will break. The material being used is just one part of the equation.
The real issue is workmanship. I absolutely don’t believe that kydex is just “two pieces of plastic riveted together”. There’s a reason some companies are considered safe bets while others a gamble - whether it be durability or being able to quote an honest lead time. The “safe bets” will see great success while others struggle to keep up.
As far as belt loops, there are many factors in whether they will hold up or not. I’m not going to cover all of them - because some lessons need to be learned the hard way by the multitude of kydex shops coming to the scene. I think belt loops are the HARDEST thing to get right - and the most important aspect of the holster next to the draw.
One is thickness. The PSI ratings of the different grades of kydex are very high. There is some “give” in kydex that is safe. Go past this safe zone - and the plastic is fatigued. Think of putting a softball on a piece of cellophane wrap. It will sag and eventually bust through. Even though it didn’t initially break - the wrap is still fatigued. Now add several more pieces of cellophane wrap - and you will eventually reach a point that can hold the softball forever without breaking.
Two is color. In plastics, colors are always softer then black. You can run PMAGS over with trucks and they hold up - but then you will hear about the Dark Earth ones having their feed lips crack. Colors have a lower threshold of fatigue.
Three - and in my opinion most important - is workmanship. When I see a picture of broken belt loops or holsters - I can usually tell exactly why it broke. I can almost guarantee that some holsters on the market - even at 0.093" - will break. It’s usually at the spine of the sweatguard or at the trigger guard. Those who work with and really understand kydex will know exactly why they will break in this spot. I’d be willing to talk more about that via PM. But there are many factors that will make a belt loop last while others break.
Fourth is the material used. I think saying “kydex loops WILL break” is akin to saying that ARs not using a FailZero BCG will break. Kydex may not the ultimate material to use for belt loops - but on a user level it CAN be perfectly suitable and durable. It all depends on how it was made, thickness, grade, and design. On that note - I do not think Kydex T (even 0.125") is ideal, and we use a different (ie stronger) grade.
On a user / customer level - properly made Kydex loops will not be noticeably different then other synthetic loops. There is also the advantage of being able to have several different sizes and designs available. For example, a Browning High Power is a lot thinner then a Glock 21 - so it can be nice to have the belt loops reflect the dimensional differences so the holster rides closer to the body.
Now on a manufacturer / employer level - injection molded loops have the incredible advantage of saving money and speeding production up. Once the tooling cost is paid - the material is a fraction of the cost that Kydex is. More importantly though, it removes most human labor (the truly expensive part). The only way I’ve found to properly do belt loops with kydex requires each loop to be molded and finished individually from an experienced craftsman. This takes a ton of time - which means more labor cost and slower production. For those reasons, Kydex loops are a very poor choice - but that doesn’t necessarily affect the customer. The other advantage to injection molded loops are that the cost of the initial tooling is high enough to “seperate” the more successful companies - who can then try and push them as being “mandatory”.
I’m not saying injection molded belt loops are a worse choice then handmade kydex loops. That is certainly not true. But as far as functionality - they can be equal depending on who made what. I think a big problem is there is such a wide selection of kydex holsters right now, and most people can’t spot what seperates the wheat from the chaff.
For example, I recently had a Border Patrol agent look me straight in the face and say “I won’t run Kydex holsters because they push the slide out of battery”. Now this is certainly not true of any company who knows what they are doing - but this man’s experience with a company was bad enough to completely turn him off from Kydex holsters. So it’s similar to someone having their belt loops break and swearing off kydex belt loops - without understanding it was most likely a design issue. I agree that the more options customers have - the better. But at the same time, when a company doesn’t take the time to master their products - it can affect other companies poorly. The same can be said of spreading oversimplified information. I’ve heard everything from “anything thinner then 0.093” kydex on the holster body will break" to “I only use real guns because blue guns are so out of spec that they don’t work for making holsters”. A lot of times, people hear this and take it as fact - continuing to pass it around unkowingly.
I have never had any of our kydex loops break. I’ve never had a holster body crack yet (this includes many 0.06" holsters as well). The only items that have broken from my shop were 3 sets of open ended IWB Kydex clips - which is a completely different concept then closed ended loops (i.e. standard belt loops) - and most companies won’t make these for that reason. Even here I believe I’ve found a solution that makes them durable enough to last without looking outside of kydex. But if I was a customer looking for a company to buy from - knowing what I know from working with Kydex and speaking with Kydex LLC at length about the material - I’d choose a company based on more important distinguishing factors then belt loops. First would be reputation, second would be their ability to quote (or overquote) an honest lead time, and lastly their level of experience. Practice makes perfect. There are hard learned lessons that you will learn only by repetition.
Every kydex holster company is still using kydex for their hard belt loops - in one form or another. Kydex LLC will flat out tell you that if you can’t get belt loops made from Kydex not to break (considering the correct grade and thickness is used) then you aren’t making them correctly.
Sorry for the rant - but I absolutely don’t agree that using Kydex for loop material automatically means they are faulty. It’s a much bigger issue - and by using that logic we would have to start saying that “0.08” Kydex T holster bodies WILL break" as some of the lesser thought out designs begin to break over time. Magpul and Tapco both make polymer magazines. One almost never fails while the other has issues. The material being used isn’t the problem, its the design.
I do have a dog in this fight - as does the other side of the argument - but I am being completely open and honest about my experience on this issue - which I believe is to be expected on this site. I’m also not knocking any companies inparticular, and complimenting the companies who put in the time to master their trade. I don’t think it’s necessary to name who they are - because it should be pretty obvious at this point in time who knows what they are doing. If not, I hear Google helps.
Also, congrats on becoming VSM regional instructor. That’s a huge accomplishment as a trainer. I’ll be watching for the 14.5" LW BCM uppers to come back in stock. Can’t beat your pricing.
Cheers.
