Description

Glock Gen 3 G20 / 21 Magwell Adapter

Due to the G20/40 frame variances year to year it is recommended to use the SLR Glock 10mm Floor plate (Link Below)

Some frames will not allow easy mag retention in frame when using magwell. Frame to frame this can vary.

Our Glock 10mm Floor plates solve this issue.

-For SF versions only 

- 7075 Billet Aluminum

- Includes ultra low-profile billet attachment screw

- Made to fit each gen and model like a glove. No "one size fits all" like many out there

- Includes relief for Taran Tactical pin

- Will work with 10-round mags (for states with capacity restrictions)

- Will not work with back straps

Magwell screw only needs to be finger tight. Do Not Overtighten.

NOTE- install over front lip of grip before pushing rear into place.

    Glock 21SF Magwell

    1st class product! Nobody makes one of these for the G21SF. But now they do, and it's awesome. Get one. You won't regret it. I didn't buy one for my second G21SF and now I'm on the email list. Because of this product being such quality, I'm buying more stuff from SLR. I'm getting a G17 Gen 3 magwell for my G17RTF. Also one for my G19RTF FDE. Multiple mag extensions for every Glock I own too.

    Solid and subtle piece.

    A perfect fit for my Gen 3 G20SF. No reworking or trimming of any material off the Glock or magwell. This is a straight install. No gaps and fitted well without force. I'll buy another for my Gen 3 G21SF very soon. Definitely extra protection of the stock magwell edge of the pistol grip.

    Magwell

    Fit the (SF) not the large frame. Some confusion on what SF means in the Glock world. To me it has always meant small frame not standard frame. Really did not make a difference to me as had both large frame and small frame that needed mag wells. Product excellent quality and great fit. Someone let me know when they come up with a mag well to fit the original large frame Glock 21.

    G21 magwell

    I just installed this SLR Magwell on my Glock 21SF. This thing is awesome.The product design is really beautiful. I spent years looking for magwells for glock 21sf. Nobody makes them. Then I found SLR and purchased it instantly. And it works with my 10rd Cali mags with no issue. Which is perfect for me. Love it. Great product from these guys.

    great product

    Magwells for Glock 21's in .45 cal are very scarce, nobody seems to make them, nobody except SLR. I purchased the magwell for my 21 and it is just as well crafted and form fitting as the other 3 I have purchased for my 9mm Glocks. I rarely write reviews for products purchased online, but this magwell is so superior I felt compelled to do so. I also have to complement SLR on their fast shipping and great customer service. Buy with confidence, you will not be disappointed!

    Great product!!!

    I just installed the SLR Magwell on my Glock 21SF. I absolutely love it. The product design is really nice. The quality is right on and the fit is top notch! I love it. I have larger hands with a size 18 ring finger. This magwell changed the grip on my Glock 21SF from one of holding it and trying to stay high on the gun to a grip that is locked in. Fits perfect. Thank you for an exceptional product! This is the first product I've purchased from SLR, and it won't be the last.
