Question: Will this fit a glock 20
Document: fit my glock 19 great, button works nice, just like it should, not too bulky, tlr 1s. Easy to install, instructions are clear
I installed this on a Glock with a TLR-2S. Fit was great but; the button switch required very firm pressure to activate. Almost imposable with the center of the middle finger while holding the pistol in a ready position. Even harder to double tap to activate the strobe. Once the strobe is going the slightest easing  of pressure on the button (like when moving your index finger to the trigger)  would shut it off so your back trying to double tap the button.
Fantastic ! fit and finish is perfect. Very easy installation and still fits my Safariland holster. Well worth the money. Another great product from Streamlight !
Easy to install and much easier to operate than the conventional TLR-1 switch. I had concerns that it wouldn't work with the Safariland 6360 holster but there were no issues. I only had to file down a little of the overlapping plastic inside the holster for a perfect fit.
I order this attachment for work and was extremely excited when it arrived. The switch worked and fitted as suppose to,however with the remote attached it will not fit into a safariland  6304 drop leg holster w/ light attachment.So with that being said if you order this remote keep that in mind. Besides that it worked great.
They neglect to tell you it only fits Glocks. Will not fit Springfield XD or probably any other make or model for that matter. The battery cover is also very difficult to fit, not a smooth replacement to the original battery cover, I felt there was a lot of tension on the small metal latch holding it all together and it would break eventually. Bad product.
I emailed Streamlight and they confirmed this remote would fit a Gen4 G21. When I got the package it states that it won't fit the TLR-2G. My goodness, why couldn't this info be shared during the product description here or the manufacturers website? I really needed this to work because my TLR-2G doesn't stay activated after a few rounds of fire with the regular cumbersome reach and toggle switch.
While I love the light, the switch I got was WAY too hard to activate. The pressure required to keep the light on was not realistic for SD use. This was probably just a defective switch since I have also read about them being too easy to activate but that just makes me wonder about what the consistent/average quality is.Another factor is that the switch is thick enough to cause it to not fit in a holster designed for a gun/light combo.
I purchased this switch to enhance the TLR-1s I use on my duty pistol.Installation was a snap. Fit was perfect. This is typical Streamlight.The issue in my eyes is in the switch itself. It's bulky and feels like a tumor on your middle finger. The pressure needed to activate the light is next to nothing. ANY grip on the pistol turns the light on. The button itself needs to be slimmed down greatly and it should take at least solid squeeze to activate the light.
I bought this for my tlr-2s light on my glock 23. it makes activating the light and laser dot so much easier then using the toggle.
Answer: yes
