rofl@ your IM...
The bull-barreled Mark II is the best choice. With anything other than a Mark II or 22/45, you're getting into some potentially irritating problems. Everyone who does cans works on Rugers, and it's the same deal as with a precision rifle...you can get something other than a Remington 700, but it's the most used weapon for a reason.
Regardless of what others may tell you, the Ciener conversions are shit. Don't even waste your time. If you want a converted suppressed Glock, Gemtech has a setup (I can't recall the mfr, but they can help you with it) that does run and can be set up to take a suppressor. It's about $450 instead of $200, but if you have to have it, you need to have this one.
The Outback is a decent can. The only issue with it, as far as I'm concerned, is the fact that the threaded portion (the mount) is aluminum. I got an AAC Pilot instead, since it weighs about the same and has a stainless steel mount.
