I can't say much to the VTAC 9, but my MP45 turned into my favorite pistol after I did the Apex trigger and sear job on it. The trigger was pretty sloppy before and I figured, why not do the sear too, while I was in there. The sights on the VTAC look really nice, but that's secondary to a smooth, crisp trigger in my book. Maybe find one to pull the trigger and few times to see how it feels before the purchase? I think I'll be putting some Novak sights or something similar on mine in the next couple of months to finish the whole package.
