My trusty sidearm has been failing me of late and I am at a loss as to why. When I shoot it, with full mags and gas, it will shoot once but will not recock the hammer for the next shot, I have to manually re cock the gun. It does this for about 3/4 of the mag and then will shoot the last 5 shots or so perfectly. It had been a while since I cleaned it so I tore it down and wiped it clean and then re oiled everything and it did not help the problem at all. So has anyone else encountered this problem or have ideas on possible solutions? Any help would be great.
