I love my High Powers, but currently have a hot nut for the .357 SiG cartridge. I have a .40 S&W BHP and am thinking of buying EKF Fire Dragon barrels in .357 SiG and 9mm so I can shoot .357 SiG and 9mm +P+ rounds out of the beefier BHP .40 S&W platform. Has anyone tried this? Any problems to report as far as feed or function go? I don't want to spend a few hundreds of dollars making a good BHP into a jam-a-matic.
Converting BHP to .357 SiG
- Thread starter 9mmHP
- Start date
Making a 40 S&W into a .357 Sig is pretty much as easy as a barrel swap, mags and extractors/ejectors are the same since both have the same size ctg. head. Going from 40 S&W or .357 Sig to 9x19mm would be a totally different story since the case head is a different size so you'd need a new slide as well as a barrel. Personally, I like the .357 Sig a lot more then the 40 "short n' weak" any day of the week. 
P.S.
If anything the .357 Sig should function and feed even better then the 40 since it's a bottle necked round.

In some cases, a .40S&W to 9mm conversion will work with only a barrel swap, it depends on the design of the gun and I am not familiar enough with the BHP to say one way or the other. I know that Glocks can be converted from 40 to 9 with only a barrel swap. Usually the maker of the conversion barrel includes a caveat in this case that extraction may not be 100%, but typically they work quite well. I would NEVER consider one for self-defense though.
I would forego the 9mm then since I already have a slew of 9mm models, the .40S&W model is just better able to handle +P+ abuse. Has anyone actually tried it and have good or bad results to report? I'm looking at the EFK barrels as Bar-Sto doesn't appear to stock the .357 SiG conversion currently.
Frankly I'd wait until the feeling passes. BHPs probably won't hold up. In fact most 357 SIGs don't hold up under heavy use. You might get 25,000 rounds through a well-made gun at best. It's really too bad because the cartridge is a very accurate and potent one. I've fired one of the fancy SIG Sport models and it was outstanding. If you have the money that might be an answer.
