Anyone who shoots SA or DA/SA use the back end of the firingpin to sight/aim? I've found it to be amazingly accurate and so much faster to acquire without the necessity of closing one eye. As long as I hold my shooting hand directly out in front of the corresponding eye the natural point of the gun in hand seems to do the rest. It's actually quite amazing. I've never had much accuracy until now, using this system. Makes no sense either. There's no sight radius to help, so I've yet to figure how this plays. Maybe it allows me not to over think it and trust my natural pointing instincts...? Very curious, but very exciting at same time. I'm going to test it at further distances next time I can find some Damn ammo! Lol Thus far I've only attempted at the typical 10-20ft. However, and also, I find its easier when shooting on the move to keep target acquired and aim on spot. Now I've got one gun I'm going to have to remove the Bluing from this spot on so there's enough contrast to quickly gain sight of. Anyway, just a thought and curiosity.
