So why'd you sell the FNX ?
I actually have sold all my FN's -- well, sold off all but one that's currently for sale, the last remaining of my former FN collection is a FNX-45 in FDE that's listed for sale.
Driven primarily out of falling out of love with the SCAR platform and the lack of innovation from FN, and falling head over heels with the CZ platform (and Dan Wesson by extension).
I don't think the Discretion is a direct replacement for the FNX45T by any means. However it's a very high quality suppressor host that I really enjoy shooting and so far runs just fine for me.
I actually prefer the HK45T that I picked up to directly replace the FNXT, and between that and the SP-01 threaded... and the Discretion... and the Scorpion... i've got enough hosts for my Octane to keep it happy
