We are on the same page. A play gun for the range, small is good.
Last round hold open is very important to me. That and the Pinocchio barrel are my only complaints with my Thureon Defense Carbine. Thanks for the heads up on the iRUNguns PSA PSX which doesn't have it.
I like the barrel length, hand guard, muzzle device set up on the FX9 the most, but the way they cut the low/rear of the lower, doesn't look like beaver tail grips will work on very well.
I'm pretty sure I have settled on the PSA PCC from Al Flaherty's, although it is about 50% more than the FX9. It does have Raptor charging handle already installed, and improved trigger.
I will likely switch to a Magpul ACS stock regardless of what I get. I have one on my AR and TD carbine, and really like it.
I've been running a Magpul MIAD grip on my AR but switched to a MOE K2 on the TD a few years ago, and like it too. I've heard good things about the BCM Gunfighter stuff, so I will give them a test run before making any decisions.
Also agreed on the insta-smile of virtually anyone who has shot my TD. PCCs are great fun guns for all. No "only a 22" stigma, a good punch but not too much recoil.
