FNX-45 High Power Caliber Conversions - Woods Defense Gun

I am interested in the FNX platform for a woods defense gun. I have heard a lot of good things about the gun. I intend on using it for woods defense for 4 legged and 2 legged critters (Sasquatch).

I would like a round with more power than the 45 ACP. The 460 Rowland and the 40 Super conversions have caught my eye and I think it would be awesome if everything worked properly with this platform. I was really excited about everything until I made a phone call to EFK Fire Dragon today about one of their 40 Super Barrels.

The lady I spoke with on the phone told me that they don't have any 40 Super barrels in stock and that they rarely produce them because there is a very low demand for them and they end up sitting on the shelf for a year before they sell. They don't have any plans on making them anytime soon. She is keeping a list of people who are interested, so if you are interested give them a shout so we can get some made up.

I then started asking her about other options and asked if they ever made any 460 Rowland barrels and she said that they used to but they stopped. Why, I asked. She said because the round was really hard on their test guns and test shooters. It would crack the polymer frames and the shooters complained about the recoil.

Maybe it's just me, but I can't really see the gun kicking so bad that the recoil is unbearable. It's less power than a 44 mag with a comp - I would think it would be kinda mild; somewhere around a standard 45 acp maybe? Maybe they didn't have them setup with comps or buffers? Nevertheless this report scares me pretty badly that I would crack the FNX frame or cause some other damage. I was thinking about a conversion kit from 460 Rowland.com

I am also considering the Glock 20 in 10mm and the Glock 21 converted to 460 Rowland or 40 Super. There are a few cons with the Glock IMO though which make me like the FNX more: The glock has a worse trigger, lower capacity with the G21, and a huge grip.


Questions:
I was wondering if anybody had any positive or negative experiences with such conversions?
Any other suggestions on conversions or other platforms which may be good for what I'm after?
Anybody know where I may be able to find a 40 Super barrel for sale?
If you do have this conversion, was it hard to get it to function reliably? What did you have to modify/do to get it to work properly? What ammo were you using?
Are the EFK barrels quality?

Any help is appreciated!
Thanks!
