When I first bought some Underwood ammo with the 140 grain Xtreme Penetrator bullet I got HUGE smilies with my G40 a friend's G20 and a RIA 1911...the first round over the chrono with the 6" G40 was 1701 fps...! Contacted Underwood and they sent a pickup order...they replaced all the ammo and the next batch was 100 fps slower which is about where it should have been....
Have been using their ammo in .38 Super, .380, 9mm as well as 10mm...will be ordering more soon...
