CZ 75 barrel issue

[chris in va]

I've come to the conclusion that my CZ's barrel chamber is a different spec than most other 9mm's I've come across. Trying to get different lead bullet profiles to feed, most get jammed against the transition from the chamber to where the casing rests (whatever that is called).

So my question, is it possible for a smith to somehow machine it out a bit to accept these bullet profiles like my other 9mm guns do? Cheaper to just buy an aftermarket barrel?

For example, I have to load these at a very short OAL for the CZ compared to my Kahr, Hipoint carbine and P11. They even chamber fine in my friend's Sig 229. The bullet shoulder gets wedged and won't chamber fully.

Sure, a gunsmith could run in a SAAMI standard chamber reamer, which might let you use your choice in bullets. If it didn't, a throating reamer would certainly let you shoot anything reasonably suitable.

Thank you. In your experience how much does a service like that cost?
