I have had the Sig Sauer P229 in 40 S&W barrel and the 357 Sig Barrel. Purchased over 15 years ago. It is an outstanding firearm.
The 357 Sig Round is excellent. When shooting the 357 Sig, either at an indoor range or outdoor, I found the noise of the report
to be above average. I wore a set of in ear plugs and put electronic muffs over them to dampen the sound. Over the age of 70,
I have lost high frequency hearing. Now in Belltone mode. Never used reloaded ammo. Still the 357 Sig is one excellent round.
