So many awesome aspects but two critical flaws - CAA MCK Micro Conversion Kit for Gen 1 Glock 17/19/19X/22/23/25/31/32/45

First off, this thing is so much fun to shoot with. It is incredibly ergonomic and really helps increase accuracy when shooting your Glock. All the good things people have to say about it are largely true.

Now the negatives: it doesn't hold zero well when moving your pistol in and out, and the shroud and the back pressure it causes will make you need to clean your weapon pretty much every time you use it. As a result, this isn't really as useful as a lot of other comparable systems like a 9mm chambered AR. If you take it to the range to zero it, you're going to want to clean it. But if you clean it, you're going to throw your zero off.

Its two tons of fun if you're simply enjoying it for target practice, but if you plan to actually use it the cleaning and upkeep make it kind of hard.

I do think this would probably be better if you got an extended barrel for your pistol, so take this with somewhat of a grain of salt.
