Hey boys and girls...... I need some help on some good ammo for my sig P6. I went to the gun show at the expo ctr. and bought a box of 9mm hydra shocks jhp and some cheap federal 95 grain jsp. I get home and i looked at both kinds of ammo and realized the hydra shocks were longer. Now i've read online that some sig p6s dont like jhp ammo. On my slide it has 1/81..... i assume it was made jan. 1981..... anywho, i went shooting and sure as s**t i had jamming issues with the hydra shocks..... would not feed, it would just sit there by the feeding ramp keeping the slide open (it still shot the hydra shocks. 80% of the time)..and smacking the slide from the back didn't do anything. I shot the federal jsp ( hallow point with lead filled tip...almost looks like a fmj) and i had a few feeding issues. I also had some blazer fmj ammo and that shot best....still one or two FTF. I was told that blazers shot dirty and the sig was dirty but i doubt that would cause jamming issues. The pistol was cleaned and lubed prior to shooting. I got one factory used mag that came with the pistol and i bought a pro mag and the pro mag did good but i had FTF issues with both mags. I have cycled rounds through the gun without fireing...... don't have issues..... since my factory mag was old i pulled out the spring and stretched it a bit prior to shooting the sig. The pro mag spring was not touched. Does anyone have a sig p6? And if so what ammo do u use? I just dont wanna use fmj and have it go through the bad guy and hit someone else in a self defense situation. Thanks guys and galls.
