Not much experience with IHZ shotguns. Let us go to Mike George and The Shotgun Handbook (ISBN 1 861261578). "The Russian-built Baikal is one to the working horses of British shooting. It is cheap and cheerful as well as being efficient and long-lived..."though the steel is quite basic it is very strong. The original factory woodwork is often rather short in the stock for British tastes and most stockers ay it cannot be bent....The main enemy of the Baikal is dirt, which may make triggers and ejection sluggish. There are no particular mechanical drawbacks, although some older guns have rather greyish blacking.
Best Buys
All the guns are strong and long-lived, although the machining on some models may be somewhat rough. Favorites are late-model, single trigger Model 27Es with the Italian (wanlnut) woodwork."
