I posted about this gun in the official picture thread, but thought it was worth having it’s own topic.
So, yesterday I picked up my first (but not last) Full Size Dagger (S) (FDE with black slide). I immediately swapped the slide for one of my other Dagger slides, this one with a Holosun dot and a Faxon match barrel, and also added a Streamlight TLR7a. This setup looks pretty sweet, if I do say so myself.
So let’s talk about that full size frame and the ergonomics. Whole E, WOW! I am 50 years old, and I have not once in my whole life ever held a gun in my hand that fit me better than this thing does. I have gorilla sized hands, so almost every handgun ever made feels like it was designed for smaller hands than mine (probably because they are). But they might as well have used my hand as the template to make the mold for this thing, just … wow! It doesn’t just fit comfortably, it lines up exactly with where it should for me - practicing my presentation with my eyes closed, every time I open my eyes to find the red dot in the center of the window, both one handed and two handed. I’ve never had a gun with a dot on it I could do that with, even with a lot of practice. You can see in the pic how well it fits me.
Also, for whatever luck of the draw, the full size frame came with the nicest trigger out of the box of any of my Daggers. It’s actually nicer than the one in my FDE compact that has a 3.5lb connector, 6lb return spring, and some light polishing on my part. I presume that’s more luck of the draw than anything to do with the full size frame, but I thought it was worth commenting on.
The inside of the magwell is ever so slightly tighter than 2 of my magazines preventing them from dropping free cleanly, but all the rest of my mags do drop free clean, so I think it’s the mags in question more than the Dagger itself. And it’s nothing 90 seconds with some sandpaper won’t sort out, so no big deal to me (but worth mentioning in a review).
So after being really impressed with it as described above, I took it out back with a 21 round Magpul mag (+1) for a quick function test. Set the target at 15 yards, and then dumped the mag as fast as I could get back on target and pull the trigger between shots; 1 second or less between shots. The results are posted below. Yeah, yeah, I know - I am pulling down and left fairly often (about 25% of the time), but I’d still hate for someone to shoot at me that accurately!
So this is probably the final form for my “Red Dot Dagger”, other than maybe a fiber-optic front sight. There is nothing else I plan to do this one, other than see if I can go bankrupt shooting it. 
I imagine this one will have a brother or sister or two coming in the near future; this is just too perfect for my hand, and too affordable at $300-ish, for me to not have 2 or 3 (or more) of these around.
Huge kudos to PSA - this is a home-frigging-run, IMHO.
