It had issues. I just spoke with someone at the range last weekend that had one. He said it was very ammunition dependent, but when using quality ammunition he never had any issues.
My first thought was it would be great for training. I looked at one today. Because most of the slide is polymer, it's a really light gun. Even though it would change the balance of the gun a bit, there should be a lead insert in the space under the backstrap to give it some extra weight.
Have one. Only have about 200rds through it, but runs good so far with bulk ammo. Bought it so my younger ones can learn to shoot on that (G19) platform/size. Fits well in G19 holsters
Seems like there are issues with it. Tim at Military Arms Channel had quite a few issues.
So I am waiting to see if there is any improvement with later builds of this model, maybe some changes will be made?
And I doubt I will buy one unless glock makes a higher capacity magazine for it.
I also handled the Taurus TX22 while at the gun show. I was impressed with the feel and apparent build quality. I am not a Taurus fan, but do find that their indigenous designs are better than the clones that they do. Plus it has a 16rd mag and costs a lot less than the glock. And they seem to work well with all ammo, judging by the review vids that I have seen.
