Yeah... the CZ 75 Line of pistols is well know as being very accurate.
I can do 2 inch groups with my CZ in 9mm at 10 yards all the time without even trying too hard. If I actually focus on accuracy, I can get it lower.
The CZ makes me look good.
I have seen the standard CZ 75 going for $450-500 online for the basic black... with fancier finishes it can go up to $500-550.
The SP-01 is $600 online.
For other brands... it really depends on the brand, the shop, and how high the MSRP is to begin with... its easier to discount $100 on a $800 MSRP than on a $300 MSRP.
I find that $75-100 is about average for pistols in the $500-800 MSRP range, when shopping from a good shop.
Budsgunshop.com tends to have some of the best prices online... with a few smaller more obscure sites having sales on individual models on occasion that you might find and can take advantage of.
