I ordered the Burris FF3 from Optics Planet. It was lower priced than the Vortex Venom and Optics Planet had free shipping.
Just got to decide whether I want try those maddmac bases for my Ruger Mark IV. Not sure if I should get the center mount or rear base mount.
leomort, that maddmac base is a good one. I upgraded mine and went with a maddmac base and really like it. The way tmitch has his pistol set up with the crimson trace would be ideal. However, I'm running a rail on mine because it is a MK2 and not drilled and tapped for a base like maddmac uses, that goes directly to the receiver. I should snap a better pic of it now with the maddmac base on the rail. Its nice and sleek now. I Really like that Burris FF3 red dot sight. I've been using the auto brightness setting and it works great. I'll bet you are going to like yours.
