For those of you who insist the 45 GAP is a solution to a non existent problem, I disagree.
I am not new to handguns. I've had a PA LTCF for 40 yrs. and for 30 of those carried some type of 1911 (mostly Colts).
I have small hands for a man, and the G21/G30 platform was def like a brick. When the G30SF came out I went for it. Best shooting 45ACP out of the box that I have ever owned.
Then I started reading about the 45GAP. I started with the G37, but found it a bit big for EDC. I traded it and got my first G38. Love at first grasp for me. Excellent accuracy, minimal recoil for a 45. A 200 gr Speer GDHP with 50 to 75 fps faster than the same in 45ACP, what's not to like? I have 3 of them now and 1 G39. (Yes, I pocket carry it in a Remora.) I just ordered my 2nd G39 today, should be in later this week.
I placed an order for 500 rounds 2 months ago and it was $20 less then the 45ACP. I don't think $185 for 500 rounds is too much to pay for such a great round. The fact that it is equal to std. pressure 45 ACP in a 9mm size frame, for those of us who do have smaller hands isn't such a bad thing.
Is the GAP going to replace the ACP, no not ever, nor was that the intention of Glock to that. It was simply to provide those who couldn't handle the thick blocky grips of the 45 Glocks to be able to still shoot a 45 caliber round. It has met that purpose IMHO.
If you want to own one, I can highly recommend it. For those of you who seem to have no use for it, do yourself a favor and borrow or rent one and at least try it for yourself.
You might be pleasantly surprised at the excellent handling, low recoil and high accuracy of the 45 GAP.
As always, stay safe.
