I recently purchased a H&K P30 from DGS at their new location which is very nice, shame on me for not posting on Yelp sooner.
Sherri and Jim are great people with vast firearm knowledge. The selection is vast, usable and priced very very fairly.
The appointment process allows you to actually see, feel, and or whatever to any firearm in stock with your sales person, it doesn't get any better than that.
Discount Gun Source is the best option as far as I'm concerned, if you don't see a firearm in their inventory see if they can get it for you, again they are great people to deal with.
