I will comment on the 2 things I am familiar with. As far as heavy bullets 69gr SMK for sure, most people have good results with the 77gr or the 75gr a-max but not everyone it seems. I top out with the 69gr smk bullets. The maximum overall length in my gun is right around 2.320-2.350" to feed out of my magazine. Street prices in my area are usually at least 20 percent off msrp and usually 25 percent off.
