I was digging though my stuff and I had forgotten that my Advantage Arms Glock 19 .22LR conversion kit came with such a nice case that has custom cut foam.
It looks like the kits now come with a little range bag instead of this hard case. While the case is pretty cool, a little range bag would be more practical. You don’t really want to be stuffing a dirty kit into the foam, as that would dirty up the foam.
Initially when I got the kit I planned to have the same night sights as on my carry guns installed. Later I heard it was suggested against installing steel sights in the aluminum slide of the .22 kit. After using it for a while, it became apparently that it was a good choice to have the adjustable Glock sight as you could adjust it for what ever particular ammunition you are using.
The magazine is a single stack 10 round capacity. It is disappointing to have such a big mag hold so few rounds.
To have the barrel threaded 1/2×28 it has to have a threaded adapter attached to the end. This prevents removing the barrel for field stripping or cleaning. Not a problem, just makes cleaning a little more awkward.
The ejector slides in the upper and has a hook that latches on to the barrel. When you reassemble this slide after cleaning, you will need to hook this extractor over a notch on the barrel. Easier to do than I can explain it.
After owning this for some years, I’ve not used it much.
I’ve not tried very many different brands of .22 in it, so I can’t say I’d have this issue with all of them, but the old cheap .22 I had would gum the kit up pretty quick and it would stop extracting reliably until it was cleaned.
Years ago I had a thread on Gemtech M4-02 suppressor and I tried that on this kit for a few rounds. The M4-02, being a 5.56 silencer, was too heavy for this kit. That weight caused excessive headspace and it would not reliably fire. I don’t believe this would be an issue with a lightweight .22 can.
I wanted to have a trainer with the same trigger and manual of arms as my Glock 19. This does that, and shoots the much cheaper .22 long rifle. But it doesn’t have the same recoil, or weight. Practicing more is great only if you are practicing perfectly. Sometimes shooting .22 can lead to sloppy shooting. You don’t want to be making bad techniques muscle memory.
In the end, I found I would rather just shoot a little less 9mm than shoot a little more .22 for training.
