I'm no pro or expert, but the 460 Rowland turns me on. That's a lot of power, I would check the website first. I don't remember if they did a para conversion. I know they did colt, SA, Glock, and SA XD. Paras makes awesome pistols, but I think the para feed ramp might be an issue, unless it's an older model with regular 1911 feed ramp.
