WALTHER PPQ SC w/ Streamlight TLR-7 and TLR-8

I’ve been seeing a number of reviews of the Walther PPQ SC accessorized with a Streamlight TLR-7 or TLR-8 that appear to be misrepresentations. I’ll explain, but let me first reinforce that both the PPQ SC and TLR light and laser light are excellent offerings from very reputable companies.

Both the TLR-7 and TLR-8 have the same accessory rail footprint. Both use rail keys as part of their mounting strategy; the rail key mounts into a machined slot in the light’s body that orients the key forward as shown below.


The Walther PPQ SC has an accessory rail consisting of only two slots as shown below.



What some reviewers are  suggesting to readers is that the TLR-7 or TLR-8 will fit on the PPQ SC’s very limited rail space. Doing that requires removal of the rail key on the light or light laser. Although it makes for interesting pictures, it’s not recommended . Under recoil your laser will loose its zero and your light or light laser could slide off your pistol from holstering and unholstering. These are not product deficiencies, it’s a simple matter of trying to fit a size 7 foot into a size 5 shoe. It’s doesn’t work very well.

The dimensional issue I referenced above can be clearly seen in the picture below.
