Most Helpful Positive Review Aesthetically Pleasing
I purchased these solely for looks. Believe it or not, these tiny additions to your magazines, changes the appearance of your Mk IV’s in a very positive way. I get that they’re meant to aid you in magazine changes, but that’s not why I did it. However I do see merit in that, as the hook is easier to...

Most Helpful Negative Review Better than nothing
I prefer extended mag bases in general as they give you more to grip during reloads and it’s easier to ensure magazines are seated properly (compared to flush fit bases); especially on the Mark IV where the magazine enters at a particularly steep angle and the mag well is pretty unforgiving.

2-handed grip

by JT, Verified Owner from WA, United States Written on March 1, 2026
This fits the MkIII and MkIV version of the 22/45. Can turn your mags universal if you have those specific guns. I don't have the MkII 22/45, so I can't vouch for that.

The hook is great for a 2-handed grip, that's what it's designed for. For one-handed target shooting, it looks kind of funny without your extra finger, but it doesn't hurt.

if you must have tandemkross

by MK3and4, from NC, United States Written on November 18, 2024
first off do not buy the regular mk iv 22/45 bases. I did write a review on those. I suggest you read it. but, the Tomahawks are good except for one issue. there’s a hole molded into the base before you get to the locking pin hole .. so you have to stick a screwdriver through the magazine slide and lift the locking pin up a little to get them passed the 1st hole to get them seated completely, which is a little ridiculous . once installed they are great. fyi, The hook is meant For your left hand, not your right hand ( or not for your primary hand ) if you’re wondering why the hook is so far away when you hold the gun .
Pros:
  • Nice grip
Cons:
  • hole before locking hole
Best Used for:
  • MK4
