How loud are PCP pistols compared to something like a HW45/Beeman P1, which are very quite springers? I'm interested in .177 with a velocity around 500 fps.
my Crosman Silhouette 1701P is a very quiet PCP pistol ,very accurate and close to the fps you are looking for.My Diana Bandit PCP .22 is louder,butt may be backyard friendly...The 1701 is as quiet as a springer the Bandit is a little louder,the Bandit is hard to beat for the money,the Crosman is a lot more money.All my CO2 pistols are louder than those two PCP pistols and louder than my springers.
