Most Helpful Positive Review Great magazine clamp
Works really good and holds magazines together pretty well. Keeps enough space so it wont effect the ejection but can effect the ejection port cover. If you are looking for a mag clamp for your MPX, this is the one to use.
Most Helpful Negative Review Doesn't fit magazines currently issued via Sig
I'm sure this works great for the older Gen magazines, but the description says it fits factory magazines...IT DOESN'T. The current Sig MPX K factory magazines, which are the Thrill Gen 2 mags, do not fit at all.

Great coupler for mpx

by Z, Verified Owner from MI, United States Written on April 20, 2025
Fits like a glove on my sig mpx 9mm magazines. I used it on my shorter 20 round mag.

Does NOT fit THRIL mags

by PC, Verified Owner from FL, United States Written on January 7, 2025
They seem well made for what they are. However they don't fit current issued SIG THRIL magazines. This should be updated in their specifications as well as their packaging.

3 stars for a well made product, loses 2 stars for poor marketing.

Lancer mag coupler

by Lance Warren, from GA, United States Written on August 14, 2022
These worked great. Material was very strong. Was concerned that threads would not stand up to torque of bolting it together tight, but they held up fine. Can’t wait to head to range for some mag dumps

Perfect compliment!

by Will, Verified Owner from TX, United States Written on June 4, 2022
Perfect fit and comfort. Lancer did a great job with this product. I will buy more for my other rifles. Highly Recommended and you won’t be disappointed. Adds a nice look! Skeptical at first but it actually helps. Great build quality like always. Looks great and feels great. Buy it!

Works great

by Matt, from GA, United States Written on June 2, 2022
Very secure and holds the magazines together nicely. Combine this with the Taran +11 and you have 80 rounds ready to go. I personally plan to add these to all my mags. Havent had any issues at all. Wolfhounds

Perfect fit

by J Car, Verified Owner from TX, United States Written on April 2, 2022
Clamps for coupler align perfectly with the notches on magazine for a secure grip. Does add a considerable amount of weight though with 2 fully loaded magazines. Something to consider if you don't want your sig to be front heavy.
Pros:
  • Size
  • Fit
  • Quick reload
Cons:
  • weight
Would recommend: Yes

MPX mag coupler

by Bernard, Verified Owner from PA, United States Written on August 8, 2020
Good product. Solid construction. Lacks instructions with the product or online as advertised. Will need to play around with the right side magazine height to avoid hitting the dust cover. The " X" logo design gives some sway to your MPX. Recommend practicing loading mags aa the increased bulk of the coupler changes the feel.

Lancer is Top of the Line

by Joe Racca, Verified Owner from NH, United States Written on March 6, 2020
This is a very solid, well made but still very light magazine coupler its from Lancer which is the company that makes the magazines for the MPX they are also known for there products being very well made, so they might be a little more money but you are buying the best not some cheap aftermarket part.
Pros:
  • easy to use
  • Built solid
Cons:
  • price
Best Used for:
  • Anyone
