I took my 62 EG Makarov to the range today and had many failures to fire. The hammer was dropping but no bang . When I examined one of the rounds it did not appear to have a dimple. If I cocked the hammer and tried again the gun fired everytime. The failures occured using both American Eagle and Blazer ammo. I have not fired the gun in some time and figured the firing pin was a little stuck but when I got home and disassembled it the pin was moving freely. Everything else appeared to be in good working order. I'm bummed out considering I always thought my Mak was one of the most reliable guns I owned and have been carrying it quite a bit. Any ideas????
