I waited all Thursday for the UPS man to arrive, just HOPING that my upgraded Sparrow
would arrive. I knew it would need a signature and I was working Friday. About
5pm I gave up as UPS is normally in my driveway by about 2-3pm if they are coming.
About 6:30 tonight the "Big Brown Truck-O-Love" came pulling in with a delivery.
I was very impressed when I put it on the scale. My original 22 Sparrow which has
just a few rounds through it (maybe 400~500) weighs in at 4.80 ounces and my
freshly upgraded SS Sparrow weighs just 5.15 ounces. I fully expected the upgrade
to weigh in near 6, so I am pleasantly surprised.
When I did a side by side sound comparison, the SS version has a bit louder first round
pop, but after that it is slightly quieter than the original. I have no official sound testing
equipment, but both my son and I agreed on the above statement.
