I just noticed tonight that my VP 410 has a much smaller contour than the 410 barrel I bought about 12 years ago. The VP barrel is like the old model 58. I put them both on my digital kitchen scale and the VP barrel weighs 11.5 ounces less than the older 410. They're both 22" long and have the same Pardner identification. Anyone know if the new ones have the smaller contour?
