Why not, the forum is already full of delusional people engaging in word fights on the internet.
If the OP doesn't see a point to paying more for a Glock vs. a PSA Dagger, well, then that's why PSA is making Daggers. Others feel differently, which is why Glock is still making Glocks.
My thought is that the longer you shoot and the more into shooting you get, the more you notice those small differences in quality or features, and then you get more willing to spend more money on smaller improvements. Perhaps a shooter never gets all that much into shooting or doesn't get specifically into handguns, and a Dagger or a Glock or a whatever is where he tops out. Good for him, hope his gun works if he ever really needs it. Perhaps a shooter gets into Zev and Shadow Systems and Staccato and carries a Yost custom. Good for him, hope his gun works if he ever really needs it.
Truth is, you never know for sure and certain if your gun is going to go BANG when it should. I've had Glocks malfunction, expensive 1911s malfunction. Maybe your Glock is a lemon. Who can say? No manufacturer or gunsmith is perfect. And ironically the more rounds you put through it, the more parts wear you have, so although it may have gone 5,000 rounds without a malfunction, once you've done spring replacements, can you really still say it's reliable for 5,000 rounds?
85% of these questions are all people trying to emotionally justify their decisions by seeking validation from other people, and just like you won't know if 9mm or .45 ACP, or a Glock or a Sig, or a revolver or a 2011 will be 'enough' if you need it, you won't know if a Dagger or an H&K will be 'good enough.'
