Briley made a 357Sig barrel for the Shorty 40 and marked it as such. Given the 357Sig generates quite a lot higher pressures is this something that should be done? I might call Smith about it but I think folks here may actually know better on these older guns. Opinions would be appreciated.

When I asked Smith the same question a while back in regards to M&P's they said no problem but 3rd gens are not M&P's so figured I'd ask. I never did the M&P conversion but rather just got a couple of them chambered for 357Sig from the factory. Wouldn't mind being able to shoot a 3rd gen in 357Sig.
