Can you describe the shooting effects a bit more? How is the flash and especially the extra noise with porting? I'm really interested in this and had contacted Magnaport. I asked them if they had done an R9. Here's their reply:
"
I don’t see why we couldn’t port this gun. It looks similar to the Kahr and we do a lot of those. Send in the complete top half with spring and rod. Cost is $145 + return shipping and insurance. Shop time runs about 10 days. Autoporting usually averages about 15 to 20% less felt recoil, you’ll find the biggest benefit is the reduction in muzzle rise (average about 30 to 50%)."
I like the looks of the Magnaport, but it seems to me that being on top, like yours, would be more effective.
That's my gun that Bob did up for me. In regard to the ports, that's how Bob does them and I have to say, they work great! BIG difference in felt recoil and work much better than Mag-Na-Ported guns that I have. ....
