Hellcat Pro: Streamlight TLR-7 Sub for Hellcat Fitment?

Background

Our previous articles on how to fit a TLR-7Sub on a Hellcat have been popular. But with the Hellcat Pro out, many people are asking about how to properly fit a TLR-7Sub on the Pro. Here is our recommendation, and it’s easier than printing a new rail key.

What’s Different with the Pro?

At first glance, you might think that you could fit the TLR-7Sub for Hellcat on the Pro. And yes, you can. However, Springfield decided to add a slot to the Pro frame, and move the existing slot. Therefore, the TLR-7Sub fits further forward on the Pro than it does on the regular Hellcat. Some people with larger hands may prefer that setup, but I’m guessing most people want the light snugged up against the trigger guard.

You might also think that a holster built for the Hellcat with the TLR-7Sub would work on a Hellcat Pro with the TLR-7Sub. However, Springfield also decided to make changes in their frame that don’t allow a precise-fitting holster from the regular Hellcat to fit the Pro. Springfield dropped the rail slot 0.9mm, which means that a Pro / Sub will bind in a holster built for the Hellcat / Sub.

These two problems make fitting up a light and finding a holster a real issue.

Solving the Spacing Problem

We have two options for you to set the light closer to the trigger guard, having it fit similarly to how it fits on the regular Hellcat.

The first option is to buy a TLR-7Sub 1913, and fit it with the #5 key. This places the light closer to your trigger guard. Replacing the key is as easy as removing the screw, removing the old key, placing in the new key, then replacing the screw. When done, your light will look like this.

If you’ve already purchased the TLR-7Sub for Hellcat, you have Streamlight’s #6 key, not the #5 that provides a better fit. I’ve asked Streamlight Customer Service, and they’ve said that if a customer wants a better fit, they can contact CS and ask for the #5 key. Streamlight has also told me that they prefer customers use the TLR-7A on the Hellcat Pro, but I shared with them that most customers who buy a Hellcat Pro want to have a similarly small & slim light solution. Further, my testing reveals that the TLR-7Sub performs every bit at the level of the larger TLR-7A.

Either way, when done, your fit will appear much better.

Solving the Holster Problem

As stated above, the changes to the Hellcat Pro frame necessitate a different holster solution. Werkz has come up with molds specific for the Pro with the Sub. This holster works with either the 1913 or Hellcat versions of the Sub. It fits best when fitted with the #5 key.

This holster also works if you use the #6 key from the Hellcat, but you may notice a slight gap through the area covering the trigger guard.

You can find these holsters by going to https://werkz.com/ and using the holster finder to specify your Springfield Hellcat Pro with the TLR-7 Sub. Werkz is currently offering for left and right hand shooters, as well as offering both IWB and OWB solutions.
