The classic way is to become an aficionado/expert, and really picky.
You don't want a Glock, you want a gen3 glock27L with blue tritium sights and lion head motif engraved on the slide al la a traditional Turkish cannon. You don't want a 44 magnum revolver, you want a three-screw with fossilized walrus ivory stocks, silver washed screws, a platinum front sight blade, and a 3/4 bobbed bone case hardened hammer . You don't want a desantis holster, you want an IWB holster hand made by Pat Boone's ex-therapist, or maybe of tanned yorkie hide (best holster material in the world, don't even think of arguing unless you have tried it), with a 22.635 degree cant and level VI retention
If you are picky enough you'll never find anything good enough to spend money on and, well, I won't say you'll be happier but you won't spend as much.
Kidding aside, that's kinda what I do without being all fancy about it. I'm not tempted by most of what I see in the average gun store, not because it's bad, but I look for special guns. The last two guns I purchased were on my want/can't find list for an average of 7 years.
