Wait... I didn't realize a .357 sig shield was a think. Interesting. What made you choose the .357 sig over 9mm?
The main reason was I wanted a single gun that could shoot multiple calibers and the 40 shield was the best choice (for me). After shooting all three calibers out of it, I decided on 357 Sig as my default carry choice. Only downside is ammo cost and availability.
That's interesting! Did you have to change anything besides the barrel?
Only the barrel needs to be replaced. The spring is stock and so is the magazine.
Wow, I didn't realize there was such a thing either.
I carry .357 because I don't trust 9mm to stop the threat. Great practice round though.
I might have to look into that set-up, as my wife was considering the Shield as a carry gun. Quantico has good prices on the gun in their LEO/MIL list.
I also have a threaded 9mm barrel for it. Same spring is used, but with 9mm mags. I love my Shield for its versatility. (Make sure you get the Shield 40 and not the 9mm.)
