re: CZ100 Series
Actually, the CZ110 DA/SA is fairly popular among those that can get them.
Over at the CZ Forum, some innovative ideas have been put into play to address the CZ100 trigger by doing some traditional polishing and/or adding home made trigger stops to shorten the travel...others indicate that after several hundred rounds the trigger improves (or the shooter has adapted).
The CZ100 in 40S&W is widely acknowledged as undersprung...as I understand it, a CZ Compact spring in the 18-20lb range has provided good results for some.
The CZ100 series is one of those hit or miss pieces...loved by some, loathed by others...
Best Wishes,
