P239 in 357 SIG, Barrel Swap Question

[theLEMband]

I've been looking for a P239 in 357 SIG; but, they aren't too plentiful in that caliber. So, I thought I would pick one up in .40 and do a barrel swap.
Has anyone done this? Were the sights good without adjustment?
Thanks,

I have done many of these type of conversions , Not on a 239 , But many different 229's and other makes and Models...Now days most are a drop in conversion...Sight alignment-?...At the distance most people shoot hand guns you will not see much of a change , but get a bit further out you will see the difference... 357 Sig has much more velocity , A lot less trajectory...

Be aware that the Sig manual specifically states you can change the barrels to change caliber (between .40 and .357) but you MUST use .357 magazines with a .357 barrel and .40 magazines with the .40 barrel. They might just say this to sell you more $50 magazines.

I've got a P239 in .357 and like it a lot but I'm thinking about going the other way (.357 to .40) just for practice rounds, I'm leery about shooting my .357 as I might now be able to find more.

Thanks for the info.

Cycle, what type of trigger do you have. I'm trying to find out what people think about the DAK.

I use my 40 mags in my 229 and they worked just fine with the .357 sig bbl

One of the fastest hand gun caliber totally accurate, plenty take down power. I feel one of the best round one can shoot. Swapping the barrel I thought @ this called Sig answered yes can be done buy original parts of course. Fitting is my concern and if it was design and fit originally for a particular slide one should run some test before actual firing in different barrel. I drop in the 40 s&w but never actually fired, a little reservation. I worry @ cambering feeding... I do understand 357 sig is neck down 40 as I do reload.

357 clock in @ 1200-1350 feet per second accuracy I have o issue. I would venture to take a shot clear beyond 80 yards
