Frankly I think porting is a waste of money and all it really does is make an already bad earsplitter an even worse earsplitter.
That can easily lead to wiffing your shot on a game animal due to unconscious flinching.
I bought a pair of Cabela's electronic muffs back in November.
I will NEVER hunt without them again.
They can be adjusted to amplify abient sound and instantly shut down when you fire a shot.
These things are an absolute god send.
If we had these when I was younger I would not suffer the hearing loss Ihave now.
I wore them on a cold, windy, Iowa pheasant hunt and they were fantastic.
I went for a woods walk this morning with my little .357 Trapper lever gun.
The electronic muffs amplify sound and you can hear a squirrel scratch his (censored).
I can shoot stumps, tin cans, dirt clods and have a ball without hurting my hearing.
In my opinion anyone shooting anything louder than a .22 r.f. should own a pair of these marvelous gadgits.
In cold weather they keep your ears warm and you never worry about the muzzle blast again.
The prices are comming down on these things and what did cost a couple hundred bucks I paid 83 bucks for.
Since then I've seen them for as low as 39 bucks.
These should be in the 'necessities' equipment list of any shooter and hunter.
Handguns are even more brutal and hard on the hearing than the largest big game rifles.
The little trapper was pure fun to shoot today. I really enjoyed getting out knowing I would not suffer ringing ears after evey shot.
Think about it.
