Welcome!! Just get an SB2 357Mag or have an accessory barrel fitted to an SB2 frame and have it rechambered to 35 Rem, it works very well and will cost about $100 for the rechamber, mine shoots excellent, if done on an extractor barrel there's nothing to change except the extractor itself, if done on an ejector barrel, a lift button must be installed, that's covered in the FAQs and Help which is where you should spend lots of time reading learning all the things you don't know about Handis.
