Customer Images
This is a solidly well-made piece of engineering design and production; I am very impressed. Have not had out to the range yet, but I can tell you that I am 10/10 excited about this as a viable option for the Glock 21 platform, and, as a platform for the many other handguns that META Tactical supports with their products. Extremely functional, extremely well-thought out, designed and created, and it gets a solid A+++ from my end.
Runs smooth and flat it’s fun at the range
Absolutely love the platform looking at building another one out for my wife it’s her #1 favorite!!
Pretty cool with 45acp. Reaches out with substantial power, makes a tempting tandem to keep handy either in my vehicle or at home
Fairly easy to use and set up. Fired 200 rounds so far and no issues aside from user error. Safety is a great addition, just have to remember when it’s engaged.
