We call that an "over rail". We don't currently have one for a Glock 21 that has an existing rail. From the bit of Googling I did, the Gen4 MOS already has a built-in pic rail so you would have no need to add an accessory rail.
Does anyone have any suggestions for a holster that will fit a Gen 2 Glock 21 with the Recover Tactical rail and a Streamlight TLR-1 or a Surefire X-300 A?

Yep, as long as it doesn't have a built-in rail
Do you make a rail adapter for the Glock 21SF? Or for the Walther PPK/s?

The GR21 will fit all versions of the 21 that do not have a rail. We don't have anything for Walther at the moment.

Fits the Glock 21 Gen2 like a glove. No slide scrub or binding that I can see or feel. Be aware as Steve said above it’s going to drop the light down some, lowering the light controls down a bit, but not TOO much. The Olight Baldr Mini controls wouldn’t clear the trigger guard portion of the of the part but was an easy fix with a hacksaw and file. Took all of 5 minutes to modify and noone would even know by looking at it unless they work for RECOVER. It’s a great option for anyone with an old GLOCK with no rail. I wouldn’t hesitate to buy it again. Well done RECOVER!

I wish I found this product years ago. I just re-fell in love with my Gen 2 Glock 21.
Brian (verified owner) –
This worked great, installation was easy, and I put and Olight flashlight/laser on it. My only complaint is that with the Olight laser I bought, the on buttons rub up against the lower part that wraps around the finger guard.
Big Mike (verified owner) –
Quick delivery and quick, easy installation. Fits perfectly. A great solution for adding a rail to a Glock 21, series 2.
William Carroccia (verified owner) –
Confused at first as it came in a box that said Glock 19, however, it has same GR21 markings as images on website so I assume it is correct. It fits well with a very small gap at bottom of the front of the trigger guard, it doesn’t impede the travel of the slide and makes it much more comfortable to shoot. I do not yet have a light for it as I am vexed on which one to get plus I have no experience shooting with lights on handguns. She will head out to the range on Sunday and see if it holds up to the recoil and muzzle blast of the big 45 ACP. I was thinking maybe some blue locktite might be in order but I did not put it on until after I see how things go Sunday.

Very Easy to install, took maybe 3 minutes to complete. Works great. Would buy again.
Karl R Hopfer (verified owner) –
It fits the G21 perfectly. Took all of 5 minutes to mount. I installed a tactical light with laser on the rail without issues. Nice tight fit with no light shake/movement. I really recommend this if you want to put a light or laser on you smooth frame Glock.
Bob Crumley (verified owner) –
Fast delivery, fits perfectly and looks great. I’ll be really happy if and when Olight sends the laser/light I ordered more than two weeks ago…
Steve Simpson (verified owner) –
I can finally put a flashlight on my G21 gen1, great product love the design and fitment. Works perfect with 45acp but when I switch to my .22 slide it binds and doesn’t allow the slide to close. Another issue I came across is no options for a case other a custom case . they sell cases for the g21+olight PL mini 2 but the the adapter on there it lowers the light down an additional 1/4 in or so… Recover Tactical has a slick clip holster but with the addition to that the light would have to relocate..

(Original) Kann man nur empfehlen, absolut passgenau sieht gut aus und das wichtigste es hält.
(Translated) I can only recommend this product, absolutely perfect fit, looks good, and most importantly, it does what it’s supposed to do.
A.J. Kritzman –
Works as advertised. Can’t ask for more than that. Easy to install and just as form fitting as the Recover Tactical rail adopter for the Gen 2 Glock 17. So, breath new life into your Gen 2 Glock 21 by giving it the ability to accessorize like its younger brethren. Don’t be left in the dark!
