I’ve been running the DAA medium bag for about a year now. Previously was using a standard range bag like the Midway one
The DAA medium is great holds everything I need and more
Don w/ Venom Customs makes great guns. He's built me 3 open guns and worked over my STI matchmaster. Don does phenomenal work and he is such a great guy. He can do pretty much anything under the sun.
Most of the people I shoot with run the DPP and they have no problems. I'm running a Vortex Razor on my G17 Gen 4. No issues so far but its only has around 2K through the gun.
I think it's a must especially for traveling to a major. I've never had to go to my backup gun during a major, but always good to know i have it if my main ever went down
I started in open and never looked back lol. Started with an open glock then moved on to 2011’s. I’d try what you have now then decide on what division you want to shoot. If going to open, go the 2011 route for sure
