High Reliability Extractor Depressor for Use in Handguns

Abstract

A high reliability extractor depressor assembly for use in handguns which significantly reduces the effect of recoil on the extractor depressor plunger assembly. These positive effects are accomplished by the following: (a) designing a new longer piece (standoff bar) of greater mass, (b) redistributing the mass from the rear of the assembly to the front, (c) designing a new shorter piece (extractor depressor plunger), (d) reversing the location of the longer piece (standoff bar) and the shorter piece (extractor depressor plunger) in the assembly, (e) increasing total mass of the assembly, and (f) changing the balance of the assembly by shifting mass to the rear of the spring.

1 . A high reliability extractor depressor for use in handguns comprising
 a. a standoff bar   b. an extractor depressor plunger spring and   c. an extractor depressor plunger.   
     
     
         2 . A high reliability extractor depressor as in  claim 1  where the extractor depressor plunger is located toward the front of the extractor depressor raceway in the slide of a handgun. 
     
     
         3 . A high reliability extractor depressor as in  claim 1  where the standoff bar is located toward the rear of the extractor depressor raceway in slide of a handgun. 
     
     
         4 . A high reliability extractor depressor as in  claim 1  where the extractor depressor spring separates the standoff bar from the extractor depressor plunger. 
     
     
         5 . A standoff bar for use in high reliability extractor depressors for handguns where the length of the bar is between 1.30 inches and 1.80 inches long and the diameter of the bar is between 0.13 inches and 0.16 inches. 
     
     
         6 . A standoff bar as in  claim 5  which is slightly rounded at rear end and contains a spring retainer at the inner end to accommodate a spring. 
     
     
         7 . A standoff bar as in  claim 5  where the length is 1.66 inches and the diameter of the bar is 0.15 inches. 
     
     
         8 . A standoff bar as in  claim 5  which is made of a strong rigid material with a high density, good heat tolerance and galvanic compatibility with the rest of the firearm. 
     
     
         9 . A standoff bar as in  claim 5  which is made of stainless steel. 
     
     
         10 . An extractor depressor plunger for use in high reliability extractor depressors for handguns where the length of the plunger is between 0.25 inches and 0.75 inches long. 
     
     
         11 . An extractor depressor plunger as in  claim 10  which is slightly rounded at the front end and contains a spring retainer at the inner end to accommodate a spring. 
     
     
         12 . An extractor depressor plunger as in  claim 10  where the length is 0.48 inches and the diameter of the bar is 0.15 inches. 
     
     
         13 . An extractor depressor plunger as in  claim 10  where the bearing seat is reduced. 
     
     
         14 . An extractor depressor plunger as in  claim 10  which is made of stainless steel. 
     
     
         15 . An extractor depressor plunger as in  claim 10  where the diameter is between 0.15 and 0.155 inches and the length is between 0.15 and 0.20 inches. 
     
     
         16 . An extractor depressor plunger as in  claim 10  where the spring retention section is between 0.05 and 0.1 inches. 
     
     
         17 . An extractor depressor plunger as in  claim 10  where the spring retention section is chamfered.
