I have not. I've had a Zev and Dawson magwells and preferred the Dawson but the AA is considerably smaller. I haven't shot it yet but I definitely like the feel. The opening is obviously smaller but still offers a slight advantage for reloads.
OP
How are you liking the XC1 I'm highly considering it. Ive heard mixed opinions on it.
I still haven't shot the pistol but I've handled it quite a bit. It's bright enough for its intended purpose but doesn't have a lot of throw. The switches seem to work ok but I prefer the switches on the X200/X300 a bit better, mainly the push forward momentary on (have to press down on the xc-1). I've read some complain about the side switch for constant on but I very rarely need constant on so it doesn't bother me. The mounting solution didn't seem all that great when I installed it but its stayed securely fastened so far, as long as it doesn't come loose under recoil I won't have an issue with it.
So is the momentary on more like the TLR series then? Is that what your refering to when you say push down?
