1-You understand what the deal is .
2-The " technology " has improved somewhat in dB reduction , but not so much in relation as to how it actually works with a particular pistol, whch leads into 3
3-So true ! It's a niche market . I have heard that HK has put some resources into exploring the use of suppressors on some different HK pistols.
I don't know how far it went or if it went anywhere . Which of the 2 manu's has the most to gain ?
Well ,since you have to go through the ATF process ( TIME & MONEY )
to get a suppressor, it's probably the suppressor manu's that have the upside of the 2. Most people buy guns to shoot because of whatever attributes they find attractive on the gun . Which leads to this, a LOT of people don't see the value of owning an HK .
They can buy xyz pistol for $3.98 and be happy ,which is fine by me. How big is the market for shooting HK's suppressed ? Who knows ? The gun industry is very secretive and it's hard to develop any metrics to know.
4 is IT -If the pistol functions fine at first go with it and keep an eye on critical wear points .The RSA and the locking lug, slide around the muzzle and barrel hood ,etc . BUT .......
The problem with ALL of this you are spending ONE THOUSAND PLUS $$$ on something that might NOT work on your pistol . You would think the dealers would have some data on what works with what pistol .
If the different suppressor manufacturers don't have some kind of data base on WHO they have SOLD and for WHAT pistol , they shouldn't be in the business anyway.
My solution , like you give a rat's ass ?
These .....electronic hearing protection . Cuts off over 85dB and you can talk while wearing 'em all day long. NO sh*t in the face or mechanical damage to you or your pistol OR
Rifle . I was wearing these standing next to the muzzle and facing away by my 16" .308 AR10 platform rifle ( POF 308) with a muzzle break , I flinched a little because of the blast , the noise level was just fine .
