I picked up a SBE3 this season and once I figured out the shims its been good. Not a single hiccup and I have shot hundreds of rounds in single digit temps. I bought the wife a Beretta A300 Ultima and it has been good as well but I haven't had it out on the cold days since she is a sleep in kind of gal when the weather turns lol.

I was using a Stoeger M3500 and the only problem I had was when it got real cold the spring wasn't strong enough to strike the primer. I replaced the firing pin and hammer spring and it hasn't missed a beat.

Best thing I can say is get what makes you happy. Go handle a few different ones and get the one that is most comfortable to handle. I prefer the inertia just for the ease of cleaning and reliability. I really, however, felt more comfortable with an old A5 and if it wasn't for the cheap feel (to me) of the wicked wings version I would have ended up with that. Really like that hump back for lining the target up.
