I purchased a 75b 9mm about a month ago. The first 200 rounds were WWB (100 count box). I had about six FTE's. The second 250 rounds were CCI Blazer-Aluminum. I had about 10 FTE's with that batch of ammo.
Thereafter I picked up Wolff mag, extractor, and recoil springs(16#). I also polished the ramp.
My third time out to the range I had only one FTE with a variety of ammo including CCI brass, WWB (50 count), and Rem UMC. Not satisfied I polished the chamber.
Today I ran through 200 rounds of WWB (100 count) with no FTE's or FTF's.
Originally I was going to purchase a Mini Firestorm (Bersa) 9mm, but kept hearing about how accurate, ergo., and reliable CZ's are. After lurking for a while I instead purchased a CZ and am happy I did.
My thanks to all who contribute to this board. Your advice is invaluable.
