Well the moment you have all been waiting for. I got out to the range this past Sunday to test the 40B with the upgrades I made. I ran a total of 200 rounds through it, 100 were 165 grn FMJ range rounds, 50 165 grn HP's and 50 180 grn HP's. All fed, fired and ejected with no issues what so ever. The polished feed ramp and 18 lb Wolf recoil spring is just what the doctor ordered. The slide speed and lock up are greatly improved, it locks into battery with a nice firm feel and feeds the rounds smooth as silk. The new 12 round mags also functioned with out any issues. This by far is the best hand gun I own for the money, it's a big winner!
If any of you have any questions I'll be happy to answer them. Thanks for the support and a great sight.
