I know just about every gun in the Springfield Saint line has had nothing but problems. I know someone who purchased one and had jamming problems and had to send it back for repair. Seems to be common.
Rainier Arms Match Barrels are decent, not the best but under $250 they get the job done with decent groups. I have always had good groups with them when I used them on my builds.
So here is a fuel filter for sale advertisement from Facebook. At least they don’t hide their true intentions. Great for a 3 am knock on the door from ATF or intent you build if you own a drill bit. Pretty stupid...
