I got mine before the Compact came out, and I bought it with the size similarity to my full size 9mm M&P's in mind. It has been a great pistol.
As with all semi-auto .22's, it needs good ammo, like 40 grn @ 1250+ FPS, and it helps to keep it clean and lightly lubed. It has a failure to feed/eject once in awhile, due more to ammo than the gun. Dealing with stoppages on a training gun is a good thing anyway, IMO.
Despite the rather large grip, it is a popular pistol for my 12-16 yo grandchildren to shoot.
