H&R Model 158 Won't Fire
« on: April 05, 2013, 12:54:15 PM »
Hoping someone can provide advice on a "project gun" I bought from a pawn shop cheap.  This is a Model 158 in 16 Gauge made in 1965 according to serial number.  The hammer will not drive the firing pin to make contact with shell.  I have disassembled the receiver and the firing pin is not broken and the firing pin spring looks new.  I suspect the hammer spring may have weakened if its the original.  This gun does not appear to use a striker or lifter assembly.  Could anything other than a weak hammer spring be the cause of the problem?  Thanks.

Order a Wolff extra power double coil hammer spring, the usual cure for misfires/no fires. Transfer bars didn't happen until the late 70's.

How about the firing pin protrusion? Did you take the firing pin out, clean the bits and channel, etc.? If not, you really should. Some kind of 'dry-lube ' in there would be a good idea too.
