59 reviews for Steel City Arsenal Slim Magwell for Polymer 80 PF940C Frames – Anodized Black

  1. Shannon Richardson

    First off the price versus quality (fit/finish) is amazing, if offered by anyone else this would easily sell for another forty bucks. I have very large hands and this gives my pinky the perfect resting place, it’s also not bulky but does increase the magazine opening. Works with my Glock and Magpul mags, Taran Tactical plus 2 and Falkor plus 5 extension!
    Hope this helps anyone that is thinking about purchasing, you won’t be disappointed!

  2. Jason Williams

    This is a high quality magwell for a PF940C. The fit on the frame is snug and has no movement once installed. It creates an even better grip for me by giving my pinky a better shelf to grab onto. The magwell is shaped correctly and the finish is smooth enough that it won’t create any blisters after longer times shooting. Overall this is the best option on the market right now and will most likely remain so for a long time.

  3. Christopher Mason

    Fits just as snug, facilitates a more solid grip, and accommodates 10-round magazine! Not to mention the aesthetics are unmatched by any other brand.

  4. Kyle

    Magwell has great fit and finish. Fits perfectly on gun, and also has a great feel in my hand. Machine work is top notch, and will definitely order more of these in the future. Buy it!!!

  5. Shane

    Fit perfect, easy install, looks awesome. Will be buying 2 more!

  6. Thomas Shaw

    Got one for my full size build when they first came out. Needed top get one for the compact build. With the Father’s day coupon, how could you resist. Better than other more expensive options out there. Fit and finish are excellent. Like that the retaining screw head does not protrude out on the grip.

  7. Natt

    Perfect fit ad it worked great with standard glock magazine. This is the second one I tried. Will buy these again.

  10. Andrew OGuin

    Perfect magwell for polymer 80. Try others, this thing is beautiful fit is perfect. Highly recommend.

  11. Donnie Dunn

    This is the best fitting Magwell I have ever owned, changes the entire gun. They forgot to send my sights so I will review those when they arrive.

  12. Aaron Cratty

    I’ve purchased a handful of different magwells for Glocks to date. This one is by a decent margin my favorite. It’s the best fitting magwell I’ve experienced with the P80 frames and has just the right amount of flare for my hands to really add grip and control of the pistol. It’s also well contoured for guiding magazines home, but I feel that’s pretty standard.

  13. NickB

    Perfect fit! Looks great on my od green frame and feels great in my hand.

  14. Wolf

    Very well constructed feels very durable

  15. Jeff Frabel

    Perfect fit and finish. Installed in seconds.

  16. MJ

    This was the last piece that I needed to finnish my p80 build. The magwell snapped into place and the set screw is flush with the grip.

  17. Santiago I.

    Amazing product. Quality materials. Clean design. The ONLY complaint I have, and I can see others having, is with the standard OEM magazines, I find myself having to put a LOT of force to get it to lock in. If I don’t it falls out. Pushing forward an up works for me.

  18. Jonathan

    I had to wait a while for this to come back in stock, but very happy with the item. Fast delivery, it fits easily in and out looks good. The only thing to watch out for is that my standard G19 mag didn’t fit all the way in easily. Most of my mags have extended plates on them so it’s not an issue but something to watch out for if you aren’t planning for that.

  19. Mike Amaral

    Fits perfect on my Polymer80 grey frame.

  20. Brian

    I love this magwell more than any other I’ve ever tried. It fits perfectly on my frame, and in my hand. Highly recommend

  21. PK

    Second product I’ve purchased from Steel City Arsenal and so glad I did!! Excellent fit, finish, quality, and especially customer service!! I had an issue with the threading and they were MORE than helpful to make sure everything was great. Can’t recommend this company enough!!

  22. George McWilliams

    My new favorite magwll the fit is perfect wouldn’t change anything

  23. Bob

    Excellent fit and finish A snap to install. The perfect finishing touch to my P80.

  24. Rod

    I purchased the magwell for the Polymer 80 PF940C. This thing is awesome, and fits like a glove! Fit and finish is absolutely beautiful! I definitely recommend this product.

  25. L

    Will definitely buy this product again. It isn’t too wide so you can still conceal and not worry about it sticking out too far. The fit was perfect and the audible click when installed was a plesant surprise. Standard mags are flush with the bottom end so I would advise on mag extensions but I’ve had no issues with standard ones not setting. Good buy and cheaper than competitors to boot.

  26. Alan

    Heard about this Maxwell from KSgunguy on YouTube and decided to try it on my first Polymer80 build. Solid product, easy to install, looks great and adds to my grip being so much more comfortable. I have already purchased one for my Polymer80 compact build. Will continue to buy from this company. Also used their barrel in my V2 polymer80 build and I love that also.

  27. Al

    This is my second Maxwell for my second polymer80 build. Shout out to KSgunguy who highlighted this company on his channel. Have also used their glock 17 barrel and am just as happy as I am with their magwellls. My go to site for my builds.

  28. Justin

    Perfect fit for my p80 19 build. Absolutely no problems installing and it is very sturdy. Fits my hand literally perfect for the 19. Quality product and a more than reasonable price. Highly recommend it for p80 builds and I’m sure the oem ones fit great based on the quality of mine. Could not be more happy with the design. I do not like the bulky magwells and this one has a very sleek design that looks great. A+


    Perfect fit and finish. Happy with my purchase.

  30. Kendall Barbour

    Wow! First off shipping was quick! The product is awesome. Works better than I ever intended. Perfect fit. No screw head hanging out the back like brand Z. The angle and fitment left no room for improvement. It maximizes the opening and gives up nothing while doing. All at a great price! The question isn’t should you buy it. The question is why haven’t you already bought it! Enjoy!

  31. Ben

    These magwells fit perfectly. Now just waiting for the stealth gray ones to get back in stock.

  32. David

    Fit perfectly. Very comfortable and helps keep on target.

  33. Drew

    Fits perfectly…

  34. Sean Young

    Fit and finish are 5star, I will be ordering another two in the near future.

  35. Zachary Duffy

    The fit and function of this magwell is excellent. Just be extra careful to not cross thread the retention screw.

  36. Peter

    Very pleased with this product. Nicely machined aluminum with a good quality powder coat. Fits the G19 size p80 frame perfectly with no gaps and the set screw sits flush with the back strap. Would definitely purchase again and would recommend, nice product at a reasonable price.

  37. Steve J

    Mounts up rock solid. Attractive lines. Consistent even coating. Superb machining. Forces my hand in the exact right spot every time I grab at it. Matches perfect with my “faux-land special”. Easily worth $100 or more. Buy it!!

  38. Bonesteel

    Nice flare. Solid construction. Great fit. Everything it should be.

  39. Frederick Bryant

    Great product,couldn’t ask for anything better. Easy install and matches perfectly with the P80. I would recommend this product to anyone looking for a magwell for the Polymer 80

  40. scott

    Fits perfect and looks good

  41. Richard Correll

    Great fit, and looks awesome..

  42. Chad

    Put this on my glock 19 build. Fits perfect, no slop and looks awesome. Will put them on every build i do and recommend to everyone who wants to upgrade their glock 19.

  43. Ralph

    I purchased the black magwell for my P80 build. It fit perfectly and completed the look that I was after. Very pleased.

  44. Gary Miller

    Great Product, Fast Shipping, Perfect Fit and Finish. Buy one, you’ll like it!!! STEEL CITY is producing quality products and I will definitely purchase this and other products.

  45. jammer

    SteelCity Polymer80 Magwells are the Best!
    Perfect fit and finish. While they are designed to be compatible with Taran Tactical mag extensions, I can confirm Killer Innovations also fit perfectly.
    Two thumbs up!

  46. B

    I’m new to using magwells and unsure if this would be useful or just aesthetic. It’s both. The bottom funnels mags in and eliminates some margin of error and it looks good on the p940C.

  47. Hunter

    Fits the polymer 80 compact very nice. Great service and fast delivery…

  48. Frederick Bryant

    Normally I would give 5 stars but this time 4 since it didn’t come with a screw. Other than that, great product

  49. Shawn

    Perfect fit for Polymer80 frames.

  50. Chad

    good fit, I didn’t like the looks of the lip on the front but it’s actually more comfortable than other magwells I tried. I go for functionality over aesthetics so I’m very please with this product. The price is right too. Also, this magwell has a cut out that displays the P80 marking on the base of the grip. Others don’t and it covers this marking a little, so I like this magwell much better.

  51. Derek Murphy

    The fit, finish, and function of this is outstanding! Steel City hit it out of the park and I will not hesitate to purchase additional products from them based on the quality of this mag well!

  52. Jason Alexander

    Perfect fit!!! Looks great and functions with all magazines!!!!

  53. Jonathan

    Fit and finish are phenomenal. This magwell just makes the already prefect grip angle that much better. Provides a nice bottom ledge that cups the hand perfect. Aiding in pistol control and obviously, quicker reloading. Price point should be higher but thank you for keeping it affordable for the budget restricted young military members lol.

  54. Brandon

    Magwell is awesome. Great quality and finish and perfect fit. Can’t go wrong for the price, either.

  55. Jake

    Install was quick and easy. The product accommodates the Taran Tactical magazine extensions perfectly too

  56. Travis Purser

    It was a perfect fit for my p80 940c .Easy installation and great price.

  57. Zeb Heddings

    Opened up my box, quick quality inspection. No scratches, perfect gonna slap this on quick and see how it looks. Went to slide it on and It did not fall right on. For a min I thought here we go… I applied light pressure and it clicked right in all nice and snug. AWESOME fitment, NO gaps, Allen hole on point, Allen sits nice and flush. Inside of magwell lines up just as nice!

  58. Aaron

    This magwell fits perfectly with the Poly80 glock 19, not only is the finish great but the size of the opening of the magwell if perfectly mid sized.

  59. sws850csi (verified owner)

    The fit and finish of the magwell is top shelf and looks fantastic on my Polymer 80 G19 build. I like it so much in fact that I just placed an order to outfit my Polymer 80 G22 with one as well!!!
