I'd try to hunt down an older model (pre-2000) buckmark. The newer slide is not as robust as the old stuff.
Buckmark has better factory trigger ( plus you can flip a spring and get it down to 2.5LB), the take down is easier.
If you shoot a lot and eventually wear out a barrel ( I guess that will be at least 50,000rd
)..... the replacement barrel's are $60 a piece....
