Have you seen one ... or even a photo? It's nothing like a Colt Ace. The Armscor XT22 has the entire top of the slide machined away from the rear of the ejection port forward. It's like a Beretta 92 with even the front sight band milled off. The front sight is attached to the barrel, not to the slide.SVO said:These seem to be hard to find. I've been looking for about a year for one and no joy to date. LGS haven't been able to get one either. I would have hopes that they would be similar to the Colt Ace.
