    TLR 7sub key for P365 X-Macro

    Posted by Trevor Runkle on Feb 9th 2024

    Purchased this key for the TLR 7sub to put on my P365 X-Macro for a flush fit. Works perfect. No modifications needed. The key slides right in with no issues. Highly recommend. I would submit photos but there is no option to do so on the review.

    This is the best key on the market hands down. I've used the #4 key that comes with the TLR7 Sub and also the TacDev key. The Inception key has wider slots that fill up the slot in the pic rail completely and uses 2 slots instead of 1 like the other two keys. THe inception key makes the light feel more solid, locks it in tighter, and it also moves the light back just slightly further than either of the other keys measuring with a caliper. Additionally, the customer service here is exceptional. My package was lost while in transit. I assumed it would show up and was delayed by the Christmas holiday. After a couple weeks had passed with no movement and USPS telling me they could not help, I reached out to the team at Inception Defense and Simon responded to my email an hour later, which is unheard of these days, and had a new one on the way to me at no charge the next day. Overall a great customer experience and a great product. I would highly recommend this key over any of the others on the market.

    Exactly What I Needed

    Posted by Tracy Timmins on Dec 11th 2023

    This key is exactly what I needed to attach the Streamlight TLR-7 Sub 1913 to my Sig Sauer P365 X-Macro grip. Shipping was super fast too.

    Must have item!

    Have two of these keys to mount TLR-7subs to the xmacro. Fits great, tight tolerances and zero movement of the key in the light and dust cover pic rail.

    TLR-7 Sub Key for Sig XMacro

    Posted by Mike on Jul 10th 2023

    Exactly what you are looking for. Fits right and tight. Provides a much better seating of the X-Macro in my 4 Brothers kydex iwb holster. Ditch the key that ships with the TLR-7 and replace it with this one. You'll be very happy that you did!
