You are probably referring to the Bul M5 which comes in a variety of calibers. The Bul frame is the one that Kimber uses in their polymer series. The slide on the Bul appears to be a Kimber slide. It is a very well made gun. They make an IPSC model that is absolutely first class. If you ever get a chance to fire their 9x23 IPSC model , do it...It is a fantastic gun. The basic M5 in 45 ACP is probably the best buy in a HighCap 45ACP on the market.
