As a general rule, for Glocks, online purchases tend to more expensive than your LGS. Many advertise lower prices, but then some advertise the lower price as their cash price (Buds). Others charge as much as $40 for shipping (pure theft). And remember when shopping online, you are always going to pay a transfer fee at your LGS. So make sure you add any and all additional costs to the advertised price. You may just find your LGS a little cheaper.
Yea though I walk through the valley of the shadow of death, I will fear no evil. My rod is a GLOCK and it comforts me
