Here's my opinion and maybe the silent opinion of others who are "lurking "
I'll try to keep this brief but that might not be possible
Part of the GCA of 1968 covers "Saturday Night Specials" and some states have provisions on metallurgy of guns, restrictions on cheap, low quality guns etc. Etc etc so all the c rap guns like Rohm .22's couldn't be imported
Thus far, except for a few states that have their own laws, the ATF has let us just freely buy , own and shoot Italian import and other percussion revolvers with complete and unrestricted freedom. Front stuffers are the last hold out of the mail order, over the counter, no paperwork, no registration revolvers and rifles.
We can party like it's 1863 and pop caps all day at ranges, backyards, etc with hog legs and rifle-muskets, with black powder and caps we can order over the mail. Again, the ATF has largely left Black Powder and percussion cap sales alone. There is all this talk about ending mail order ammunition and "components " but again, black powder enthusiasts have been kinda left to our own devices and hopefully that never changes
If people start filing cases against Italian gun makers, attacking distributors, publicly bashing Pietta, Uberti , Pedersoli, etc for "ripping people off" and making a huge stink about "quality " of Italian guns the ATF may slowly turn it's head toward an area of the gun market it previously didn't really waste it's time with. Given that very, very few crimes are committed with blackpowder guns, the ATF doesn't invest much energy and man hours worrying about them. Until they start hearing a dull roar of discontent and have to look into what's going on. Instead of discontent , let's be happy with what we have. Nothing is perfect
Sometimes it's better to hide in plain view, accept the occasional lemon from the Italian manufacturers, try to buy from retailers with return policies and if the item is lower priced at a "no return " retailer, you rolls the dice and takes your chances. Rather than force Big Brother to intervene in the percussion revolver imports from Italy and start doing metallurgy tests, proofing in the US, meet "drop standards " and then the whole market is nuked .
Kind of like C&R FFLs, it's something really really good that people seem to try their best to screw up. Sometimes gun enthusiasts eat our own.
