The best guys I have found in the shops are the older guys who worked a career and are there more out of being bored and retired than for money. They may not be the most upbeat at times but if you show them respect they tend to share their knowledge with me.
Ya there's a lot o knowledge in some of them old guys. Just like me, most didn't have enough time or money to learn it all. It's nice to run into the guy that collects the gun you want to learn about. They save you so much time and expense with their knowledge. I want a good hunting gun I talk to a hunter. Police gun I talk to a cop that has been at it for years. I want to know quality then I talk to a gunsmith that has repaired a lot of guns.
If I want to get crapped on I misspell a word and let the net spelling Nazis jump
