I am ready to order a Lone Wolf Longslide for my G20SF. I'm looking for any up to date info you have on performance and reliablilty. Here are a few questions I need answers to as well. 1. Did the slide require any smithing to cycle properly? Approximate cost? 2. What sights do you have? I'm leaning towards Warren Tactical rear, HiViz front. (Target/Hunting) 3. Are you using a stock or aftermarket recoil assembly? 4. Anyone using a Red-Dot with a Carver style mount? 5. Is there anything you would do differently?
