And it worked for the 40-50 rounds of live fire I shot with it. I like the full size Dagger frame better than the compact so I'll keep it and the Remsport slide assembly to fiddle around with as a kinda-G45. The youngest boy has a compact Dagger he's happy with so I'll probably use the compact frames as trade bait (he and I do a lot of trading back and forth).
Took the CA frame as well. I like it better than either the SCT or the Dagger compact frames but the slide bite is real. I might try looking at ways to graft part of a beavertail backstrap onto the frame and use it as a backup for training classes. If I end up with another G19 it will become the spare of the "pair and a spare".
At this point I'd say they really don't do anything "better" for me than a factory G19. The Combat Armory frame is more comfortable but the inability (so far) to add a beavertail means it's going to stay in the safe while the 19.4 goes to the range.
