RE: i have an OS .40 la.
I have my 40LA in a Goldberg Eagle II. It is a good combination - more than adequate power. I also agree with the previous suggestions.... Fun 51, Mid Star, Four Star, Kavalier, etc. It may not be the strongest 40, but it is reliable, very light weight, and will last for many years. By the way, the Fun51 is a nice model - really enjoyed mine.
