I’ve asked this kind of question several times before on this here back porch of mine, but consider the following offers from our good friends at Palmetto State Armory:

Now I will be the first to admit that I am a woeful ignoramus on the niceties of poodleshooter mechanics, quality of build, materials quality and so on.
But I have to say that I just cannot see that the above-mentioned characteristics are of such moment that the SIG is three times more valuable than the PSA built-from-parts version of what seems essentially the same delivery platform.
Is it all SIG marketing, or am I missing something here?
Informed comparison is required in Comments, in other words, because you won’t get it from me.
