If already answered I’m sorry I couldn’t find it. Any future plans for mag wells, I really don’t want to spend $100 for the SLR magwell.
You can get the SLR Rifleworks Dagger magwell for $80 using coupon code “DAGGER”.
I just purchased a couple of ‘Nine lowerz, Because another gun and only slightly higher price….
(and then promptly Lost them in a Boating Accident)
Not sure if it’s okay to add to this post or should I start a new topic? Just did an experiment: butchering a Magpul MAG940 magazine well so it sort-of fits my PSA Dagger. Warning to sensitive folks: the result isn’t pretty but it might work. Attached is a sample pic. This view makes the result look better than it really is. Yes I did attempt searching for this topic before posting to make sure I wasn’t covering something that’s already been discussed to death. Some troll can tell me what a moron I am for failing to find the other posts. If someone is interested, I’ll create a new topic for Magazine Well and post more pics and process description.
I say good job. It’s an experiment and it worked. Version 2.0 and beyond will o ly gwt better. As long as it functions it’s all good. Heck how many times have we all bought cool looking gadgets that look the part but dont function well?
Thanks for the positive feedback. Like I said, the photo is kind of a glamor shot and makes the well look better. The back is especially awful because the Dagger contour is completely different, more rounded, and the little swoops or dips on the back edge seem different. Plus, the whole grip angle might be slightly different than a Glock 19 Gen 3,
You’ve brought up the key point, however, does it work. Next is a range trip to see. So far, in dry firing practice—yes I use snap caps—I notice an unexpected benefit: improved sight steadiness when pulling the trigger. Normally, when I squeeze trigger, front sight jumps right slightly (shooting right handed). If I really focus on grip, I can eliminate that jump. The lip on the mag well seems to give my hand something to bear against. The result is a slight change in the amount, direction, and location of grip pressures that improve steadiness.
As for version 2, I think I need to look at other mag wells and see if there is one made with a rear contour closer to the Dagger’s. On the plus side, the MAG940 costs about 25 USD as I type this, whereas the exact fit one seems to be in the 80-100 USD range. That’s I why I decided to go ahead and butcher the Magpul product.
One note: if anyone decides to try this, you need to poke a small dril bit in thru the screw hole and cut a relief for the screw. I didn’t quite drill through the partition at back of grip but almost. As you tighten screw, watch that partition. You will likely see it start to bow as the screw presses on it. You can also see the stress mark on the plastic. Drilling a relief hole seems to fix it. I can insert and drop magazines without trouble.
One other note: the bottom plate on the mag hits the lip on magazine well so you have give the bottom of mag a firm slap to lock it in. If you just push the mag firmly, it won’t latch and you’ll have a magazine on the floor. I could probably grind some material off the inside of well lip to fix that, or take some material off inside edge where the pistol grip contacts it, effectively moving the mag well slightly closer to the slide.
Cheers!
UPDATE: experiment failed so far. Using Magpul pmags, they drop out after first shot. With the Magpul mag well in place, magazines click into place when I hit their bottoms, and don’t come out if I pull on the base. But, the mags apparently are not quite latched all the way and I think recoil pushes them out. Now I did some grinding on the added magazine well. The pmags seem to lock with a bit less force and the mag release seems to be returning all the way. Will need another range trip to confirm.
At about 2 a.m. today, I was thinking about this some more and realized that I can my flared magwell and use it too—if I just use longer magazines than 15 round. 17 round and 33 round mags are longer and the base plates edges don’t hit the mag well add-on. Not the best solution maybe but one that simplifies the project somewhat.
I am developing a magwell for the Dagger that I should have the design finished shortly. Once I fine tune the fitment, I will start selling them on eBay. Will first be available in PLA+ plastic (what everyone uses to print frames) followed by a carbon fiber nylon for a bit more money.

I’m down. Please post when ready. The one and only thing I dont like about the dagger is the cutout at the bottom of the grip. That magwell fills it in nicely.
It looks good but will it work? I’m a buyer if they do.
this is a pretty good idea… reminds me of something i had seen in the past… doesnt it @GuitarGuy and @SuperPredator ?? lol.
best of luck to you though @jhillard32 sounds like you may be doing the right thing by selling outright on ebay and elsewhere.
lol bingo.
what are you printing it on?
Printing on a Voxelab Aquila, which is a clone of the Ender 3 V2.
Design is pretty much wrapped up, now I have to optimize slicer settings for the part. Magwell will likely leave some evidence of being installed on the frame, but this is the sacrifice that must be made for a firmly fitted part.
Not trying to Jack the thread, but this is about the Best place I can think of to bring this up:
I have a Strike Industries black-poly Magwell for Polymer80 PF40c and PF40v2 - I mistakenly purchased it thinking that I could fit it to another, not-a-Dagger/not-a-Polymer80 pistol, but that is Absolutely Not the case.
FREE to good, loving, PF40c/PF40v2-Owning Home. My Treat for shipping. My Mistake is Your Gain!
PM for Details, so as not to clutter this thread further….
Merry Christmas!
Count me in for one in black
We do not allow vendor posts here (yet). Maybe in the future.
I bought one of your mag wells on EBay and it’s a game changer. It transforms the way the dagger fits the hand and really locks it in under fire. Awesome job making this magwell. Any possibility of color matching the PSA frames in the future?
