Super stach squeed8/30/2023 ![]() The term squeezing thus refers to a reduced quantum uncertainty. Has a quantum uncertainty smaller than that of a coherent state. In quantum physics, light is in a squeezed state, if its electric field strength Ԑ for some phases Squeezed light is used to reduce the photon counting noise (shot noise) in optical high-precision measurements, most notably in laser interferometers. ![]() ![]() Today they run wildly from ‘plumb-colored’ PSPs in good condition for $600 to minty P7M13s that start at the $2K mark.There are basically two main ways to squeeze light:ĪM, when you have an amplitude (you modify the amplitude) squeezed light, you have light with an intensity noise below the shot noise levelįM, you do frequency doubling, that is you have two photons incoming into the crystal and you have one photon with doubled frequency coming out All of these factors combined make the guns extremely collectable both as shooters and as curiosity pieces. Their sleek, clean lines have long set the P7 aside as something of a gentleman’s gun. These guns are stunningly accurate, solid, utterly reliable, and have an overall interesting design. In law enforcement and military sales, the gun consistently lost sales to cheaper Glocks, Berettas, and S&W guns that were also less complicated to operate. For occasional shooters who had cut their teeth on more conventional designs, the HKP7 was often too much to get used to. With the locked barrel and low bore axis, they heated up very fast in extended shooting and just were not enjoyable after a box or two of rounds, keeping plinkers and match shooters away. These guns, with their unique squeeze-cocking lever, require a good bit of range time (and a proper grip) to cock and keep cocked. It would seem that though the gun was close to mechanically perfect it’s always been a hard sell. 40 S&W offering (the P7M10) and a double-stack 9mm (P7M13) to try to turn this around sales but ultimately failed. The NJSP was the largest LE customer in the US and the gun never really caught on with cops in the states.Ĭommercial sales, largely due to the gun’s high cost when compared to other offerings, were steady but never breathtaking. ![]() Sold more than 3,000 of the guns to the New Jersey State Police who carried them for twenty years (replaced by the SIG P228 in 2003). Who really wants to buy the world’s most expensive gun? Notably however, several German counter-terrorist teams (with larger budgets) adopted the P7 as did the German Army Special forces (KSK Kommando Spezialkräfte).ĭivided reception aside, HK never really marketed the gun right. The gun went into production first in 1979 and, while well received by law enforcement in West Germany, more departments there tended to go for the Sig-Sauer P225/P6 series than either the more expensive Walther P5 or the HKP7. Also similar to the Glock, but predating that Austrian gun by half dozen years, the P7 was striker fired. A very low bore axis (similar to a Glock) translates to super mild recoil especially when coupled with the 9mm cartridge and an all-steel frame. Weighing in at 27.7-ounces with a polygonal rifled 4.1 -inch barrel, the overall length of the pistol was just 6.1-inches. This means fewer moving parts, less to break, greater functionality, and impressive reliability. Be forced back by the excess pressure created when the round fires and means there is no need for an extractor-the spent case is chucked with a good bit of force behind it, well clear of the ejection port.
