    Sleek G20 magwell

    Wanted a slim magwell for my G20 gen 4 and this definitely fits the bill. Installation was easy without any need for alterations. Fit and finish were top notch and I'm very happy I went with this. Highly recommended!!

    Gen4 G21/41 magwell

    excellent fit, I purchased on for my G45 and liked it so much I bought one for my G21. If you have bigger hands it really improves the feel.

    Quality Magwell

    The machine work and finish of the SLR magwell is sexond to none as well as adding a great aesthetic to the large frame Glocks. The only reason for not giving a 5 star rating is the need to remove a bit of material from the magazine base plates (factory) for them to seat/lock properly. Dont hesitate buying this product.

    Does it fit Gen 3 G20SF?

    I bought the GL-MW-20-G4 To see if it would fit on my Gen 3 G20SF as there are very few options on the market. It does not fit the Gen 3 G20 SF frame. However it only takes a slight amount of modification to make it work.

    That being said I have to agree with the reviews that say it is to tight on the side of the magwell causing loaded mags to stick when dropping mags. Again slight mod to the magwell of the frame and it’s good to go.

    Awesome magwell

    It fits perfectly. I had no problems with magazines dropping, but I also have SLR Rifleworks 10mm mag extensions. On my glock 21 mags I only had one that kind of sticked. Great product as usual.

    Looks great, had some functionality issues

    So this magwell is really attractive. But Factory mags have a natural swell at the bottom when loaded which I am not sure that was accounted for in design... well makes it so I’m probably not going to use it. Full mags do not drop free, and It was very hard to load mags in because of that resistance. I tried it on my g20 and g21 and unfortunately got the same results.
    Ironically paired with the SLR magwell it doesn’t exhibit this issue, which makes me think it’s the magazine swelling at the bottom . But it’s a bummer that it is causing issues “at least for me” with factory capacity mags
