I have a 22/45 that I've shot several thousand rounds through. It's accurate and very reliable. I shoot it more than all my other weapons combined. Mine is an older w'out the grip panels nor is itr drilled for mounting optics. I've been thinking about getting a 22/45 lite and mounting a red dot site on it. MK3, 22/45, 22/45 lite, all are excellent choices that will last a lifetime.
