DVC .38 SC ports/poople holes

[Desmo412]

When I first had my FGW open gun built, I had a slot cut for holes but none were drilled. I started with 124s, as I was just learning the game and wanted to play it safe. The first time I tried 115s was a game changer. I had to send the gun back to Bobby for some repairs and had him drill 2 1/8" holed while it was there. I adjusted my 115 load back up to a 175PF ( only lost about 20fps with the holes) and the dot tracking was perfect. It always went straight up and returned to center....it just seemed to happen a LOT faster with the holes. When I have another gun built, I'm going to experiment with v4 holes in addition to some straight up....I love the concussion

SME's, how does this data on holes on a DVC transfer over to a DVC in 9mm?

I had Bobby drill 3 small holes in my 9mm FGW and don't regret it one bit.

The one thing to consider is when the slide cracks will STI warranty it after you modify their gun? They seem to be cracking between the slots so it is something to consider.

Mine just cracked... Its the 4th one from my group to crack... This does not make me feel good about my second dvc... Hope STI stays in business... I certainly wouldn't suggest milling anything more out of the slide... They just don't seem to be able to handle it as it is already

That's a bummer. did the crack promulgate from the corner of those slots on top? I'm guessing they didn't break the edge on those cuts?

[FullMetalJacket]

Last one is mine... The others are just 2 friends I have pics of... Definitely sucks, especially for the money

It looks as if they aren't setting a sufficient gap between the end if the slide and the comp. they are looking for for a seemless look, but you need at least a 3-5 thou gap all the way around the comp when in lock up. Casically the slides are beating themselves to death.

[BeerBaron]

That's exactly what I was thinking. Looks like slide is hitting comp.

[FullMetalJacket]

No marking indicating anything hitting. I see clear light all around the comp. :shrug

Warranty... They'll have to get it right eventually or go out of business trying.

Well said azgunut that is something i look at more and more add years go buy. Who is going to take care of my gun

[Mark Meyers]

I'd leave it alone and shoot the crap out of it.

Agreed, they appear to not be following some of the most basic gun smithing rules and the slides are apparently beating themselves to death. I always go the plunge EDM route for holes. It's expensive, but it's the best method. Absolutely burr less, no effect on anything but recoil and velocity.

I highly recommend porting on everything. Another problem with that particular model is that big fat comp on the end, it weighs too damn much for the lock-up time to be what is necessary for the best open gun imaginable IMHO.
