I'm sure this has been beaten to death, but searching for "Vaquero" has a lot of results and I couldn't find a good comparison. I just bought a Vaquero on Friday and didn't see much difference between the "old" and New, but the "old" felt better in my hand. What is the top of the list for need to know info about the Vaquero? Are there any must-do modifications for better trigger, etc.? I'm sure my dad is already scheming to make new grips for it, is there a good source for a cutdown frame or grip only other the the $100 new ones on Midway? Thanks in advance for any info!
