Actually the uml is lighter . I recut the breech end , braked it ,and put it on a bk92 knight because the priginal 54 barrel got ruined . Its a fabulous shooter !!!The UML 26" barrel doesn't appeal to me (probably heavier than the old style barrels). Still looking around at what I can get a light weight 45 barrel for the old ml - I don't need mega fast, just looking at light weight.
Problem is the bp would need tp be custom made for a 700ml AND its still a 50 !!!
