Excellent information about hearing protection, including a table of gunfire noise levels. http://www.e-a-r.com/hearingconservation/faq_main.cfm
Peak Sound Pressure Levels (SPLs)
Type of Gun SPL (dB)
.44 Revolver 170 dB
45 Automatic 165 dB
M-16 160 dB
.357 Revolver 160 dB
12 Gauge Shotgun 155 dB
.38 Revolver 150 dB
.22 Rifle 145 dB
Home Depot carries the red NRR 21 Stow Aways for $18. When they're not red they're sold to us as "Shotgunners" for a higher price. For $14 you can get the clunkier NRR 20 muffs.
Regardless of price, if the muff doesn't have an NRR with it you should not buy it.
