I am a fan of the Tasco Optima sight system..As all know the
Optima is no longer available,there is a similar sight the
J-point but I found that lacking..Well there is a better sight available but it is a bit more expensive..
Enter the Docter sight,,It is a bit bigger than the Optima and a little heavier..It is made of metal and glass where as the Optima was all plastic..The dot is brighter and doesn't fade out in dim light as the Optima does..
I have only about 200 rounds through the CZ75b with the sight on it and it is a joy to use..The adjustments were easy to do and then lock in place..There was no movement after sight in..Only time will tell how much better this system is over the Optima but I have had no problems with that system either..Everything points to the Docter to be more durable in the long run..IPSC shooters claim it is superior in all ways but I will withhold judgment till I have a 1000 rds through it..
In conclusion I can say I am well pleased with this sight and
will enjoy it immensely
