I own two Bul Open guns. I use a Bullesteros as my primary and a URF as my backup. My logic when I bought them was "for $8000 I can get TWO guns so I have backup if one goes down for the price of one Infinity." That scenario is currently in play as my Bullesteros had a catastrophic failure at Area 5 this year (cracked frame rail). Bul only has a 1 year warranty on their guns. Even though my gun was "2 months over" warranty they agreed to service it for me. It's currently at their USA division being evaluated (no word yet). I don't think it's unreasonable to expect even a $4800 Open gun not to suffer a cracked frame rail after 10,000 rounds so I hope Bul "makes me whole." Maybe I'm wrong.
Bul no longer offers the steel grips on their OPEN gun due to problems in their two part design. Polymer only. Keep that in mind if it's an issue.
I love the way my Bul's shoot and feel. I hope they come through.
